We examine the the ins and outs of training plans and the ways they can help or hurt our short and long term goals. We discuss plans in general and our approach, and tackle items like adaptability and rigidity, goal setting and expectations, time in zone distributions and more. We also answer your listener questions.
This episode deconstructs a recent study showing unexpectedly low reliability of individual training responses in people undertaking the exact same training program twice. We go down several avenues of reasoning for why this might be the case, apply these lessons to trained cyclists, and answer your listener questions.
We talk about the summer slump that many cyclists experience, where it can originate from, how to think about maintenance to balance event demands with training and more fun, unstructured riding, and how goals and expectations can come into play. We also answer your listener questions.
We delve into the recent large scale replication project in sport and exercise studies, their methods and findings. Then we try to understand why it found the results that it did in light of known statistical phenomena, similar findings from other research fields, and why an apparent replication crisis depends on how you already view and interpret published literature. Plus your listener questions.
We reveal our process for dealing with the uncertainty inherent in training and racing by keeping the FO in the scientific method of FAFO. After addressing whether or not probabilities are even real and the role of subjective experience, we look at some examples of uncertainty and predictions in testing, training, and racing, how reliable and accurate that data and performance models may be, and the process of improving our confidence in their ability to guide a training program. We also discuss incorporating peer-reviewed literature as well as anecdata, and the ultimate value of coaching or self-coaching experience.
We discuss planning race preparation and how it differs from a general aerobic build, periodization considerations, B vs A priority races, adjusting approach based on feedback, differences with low and high training age, and reorienting goals along the way. We also answer your listener questions.
We talk about coaching athletes to autoregulate (vibes training), meaning making choices between structured and unstructured training, hard work and fun, intensity and rest. This considers the angles of athlete experience level, life stress, people who don't like rigid training structure, workout selection, and more. Plus answering your listener questions.
Exercise physiologist and performance nutritionist Tim Podlogar joins the podcast to talk about determining endurance athletes' energy needs, macro targets like protein, fats, and carbs both relative to bodyweight and total energy needs, nutrient timing strategies, glycogen loading, bodyweight regulation, and much more. We also ask listener questions on fad nutrients, hydration, and determining supplement needs.
Our three most experienced coaches discuss common mistakes when training and building FTP. We look at testing, interval execution and progression, adaptation timelines, periodization, fatigue management, lactate testing, and much more. We also answer your listener questions on FTP training.
We tackle the ideas of unique responders, the role of performance variability in differentiating training response between individuals, pitfalls in interpreting typical individual response data, and the experimental setup required to actually tease these things apart. Then we walk through a couple easy principles to apply the takeaways in your own training.
We talk about things we wish we knew earlier about training, racing, and coaching. Nutrition, skipping workouts, setting process goals, finding your strengths, athlete feedback, and more. We also find out what our listeners wish they had known sooner.
Following up from the last episode, our coaches dig into the balance between training stimulus and recovery capacity, with practical ways to diagnose which is a potential performance limiter. We also touch on low volume athletes, very well trained ones, overlapping stimuli, periodization, short and long term tradeoffs, and more.
We walk through an analysis done on almost 15,000 people with data up to nearly 7 years in length and after finding similar trends in Kolie's client and personal data, we apply what we can learn about diminishing returns to our training expectations, season planning, stimulus and recovery needs, our ultimate potential, and what it means for interpreting scientific literature.
Our coaches discuss what panic training is and how it manifests, common reasons for it to occur, ways to plan now to avoid falling into the trap, and ways to pivot before and even during panic training mode. We touch on all sorts of related topics like nutrition and panic dieting, setting milestones and assessing realistic goals, the impact of social media, and a couple ways to rethink training or goals to fit your season, plus answering your listener questions.
Our coaches dig into non-FTP related aspects of training and physiology that that lead to better race results, and workouts that can be done for each. We specifically consider road racing, criteriums, mountain bike and cyclocross, plus gravel and ultra racing, and a couple things to train that can easily apply to everything.
This episode we make our case for why endurance and recovery rides can and probably should be paced easier than expected, even for time crunched athletes. We look into the issues that can occur from riding too hard, then delve into physiology, power and heart rate zones, RPE calibration, fatigue and energy management, and more. Plus we answer your listener questions.
We take a deep dive into the published literature on durability. First a critical look at the paper coining the term, the next establishing a widely used measurement, and another on the definition and differentiation of several aspects of endurance performance. Then discussing aspects of measurement and trainability, plus the relative statistical strength in the literature vs typical interpretations. Finally some advice from coaching experience, and answering your listener questions.
can really inform our decision making. Plus we discuss the seeming need for heuristics over nuanced takes, the role of the scientific process in coaching, our favorite metrics, and answer your listener questions.
We dig into a recent study showing a disconnect between equal muscle glycogen recovery and unequal high intensity interval performance due to delayed recovery fueling, despite equal total calories. We start with some background on glycogen's structure and the importance of fueling before discussing the outcomes and conclusions of this double blind, placebo-controlled crossover study before speculating on mechanisms and potential applications to trained cyclists, and connect it to common current nutrition practices.
To celebrate over a million podcast listens we let you ask us anything, and we answered. You asked training questions about how we would refocus the US's cycling governing body, improving climbing, book suggestions, how long it takes to return to peak form, indoors vs outdoor duration equivalents, partial ROM lifts, if you need to be in a caloric surplus when training, tempo workouts, and more. We also answer more personal questions like our lift PRs and a game of FMK, music and food, plus updates on how and why our own training and competitive goals have shifted over the recent years.
, when and how to include strength training, if you should do intervals and how hard they can be, sweetspot vs polarized, incorporating fun rides or Zwift and other virtual racing, and more. We share our thoughts on what we actually consider when we're planning training for our coaching and consultation clients like off-bike stress, race schedule, fatigue management, training history and personal physiology, dealing with fitness loss and expectations for regain, plus we answer a bunch of listener questions!
Coaches Kolie, Erica, and Gediminas talk about the most impactful training habits that cyclists can incorporate into their routines, and the ways that these habits can be overdone that end up working against us. We dig into consistency, nutrition quality, health consciousness, coaching relationships, focus, sleep, and more.
Our coaches address the common question of why your friend may be faster when doing less training than you, as well as why your experience level or race category probably doesn't indicate how much you should train. We look at the different returns on investment with training volume vs intensity, selection and survivor bias in cycling, a survey of power and training volume with racing cyclists in the US, and why comparison can be the thief of joy, but when it can be a useful tool for goal setting. We also answer your listener questions on genetics, time in zone progression, training time as a limiter, and more.
This episode is one of our deepest dives ever, into the literature on creatine's effects and tradeoffs with cycling performance, and how the results fare against Kolie's standard for being meaningful, noticeable, or measurable. Because individual studies report such varied results, we instead look at a meta analysis on creatine supplementation in aerobic performance, another on repeated sprints, plus a bonus study with a simulated road race. There's also a brief and explicitly non-expert look at a popular paper on creatine and cognition. Instead of recommending whether cyclists take creatine or not as a binary, we discuss the pros and cons, realistic expectations of effects, and in what cases we would consider supplementation. Plus your listener questions!
This episode we start with the old cycling adage "train your weaknesses, race your strengths" as the jumping off point to discuss strategies for diagnosing and training weaknesses in the off season. We decide for whom this would make sense as a strategy, the opportunity cost of training a weakness, low opportunity cost things to train, how race selection factors in, and much more.
This episode we look into the published literature on the surprisingly tight agreement between FTP and RPE and a couple different lab-derived measures of threshold like MLSS and critical power, along with the concept of anchoring. But first we get philosophical about how measurements often become definitions that can lose sight of our valid observations and experience. We wrap up by discussing FTP testing with RPE, plus answer your listener questions on RPE scales and anchors, RPE drift, common mistakes when using RPE, Borg's 6-20 vs 10 point scale, and much more.
This is a deep dive into four papers on hypertrophy and strength training, and use them to find guidelines around how cyclists can improve strength without gaining weight. We evaluate the stimulus and overall impact of eccentric vs concentric contractions, sets and reps, minimum dose for strength improvements, progressive overload, and nutrition.
We take a deep look at ten commonly used ways to test or estimate FTP, and dissect how and why each method does (or is supposed to) work, how often we might expect accurate result and who it'd be accurate for, and the Empirical Cycling standards for test accuracy. We also dig into some data on ramp test accuracy and bias, plus how anaerobic capacity, RPE, and daily fluctuations in performance can play a role in test results. Plus time in zone, %FTP, normalized power, lactate tests, the "Kolie Moore" test, and your listener questions on DFA-alpha1, eFTP, and more.
Our coaches sit down to discuss the downsides of using FTP as an anchor for many types of intervals, how your individual physiology can make those targets suboptimal for the best stimulus, and the many alternative approaches that we use instead. We dig into VO2max, anaerobic and sprint efforts, plus first threshold and endurance riding. Then we answer your questions on minimum effective dose, breaking out of a rut, assessing realistic targets, and more.
Dr. Eric Trexler joins the podcast for a nuanced discussion on energy expenditure and endurance sports. He explains measurement methods, the constrained energy expenditure model and its interpretations, the difficulty of calculating your total energy expenditure and needs and practical solutions, some curious results from papers on energy expenditure in cycling grand tours, and much more.
Our coaches answer your questions on identifying limiters, how to take a rest week on a low volume plan, resuming training after a break, training for fitness vs racing, total time in zone vs structured intervals, the things that cyclists under-optimize, making the most of unusually large training weeks, the benefits of ice cream, and much more.
This is a critical look at our previous podcast episodes on VO2max training, and with hindsight provide new and additional context on those training recommendations, plus other effective ways to do VO2max training, with their coaching and contextual aspects. We investigate some instances of "VO2max blocks" in the scientific literature, reexamine the 30/15s paper, and discuss additional factors that confound the interpretation of those and other published results before considering how we can use that information to our advantage when training.
This is a practical guide to FTP training, through three lenses: where you are in your season, where you are in your training journey, and opportunity cost. In each instance we think about reasonable expectations for improvement, if you should add more power or interval time, when to switch to VO2max training, periodization strategies, and how to prioritize your training. We also answer listener questions on over unders, progressing longer or shorter intervals, block training, in-season maintenance, and more.
This is a dive into research showing increased AMPK activation with low glycogen stores. We break down a paper discerning how AMPK does this, subsequent changes to AMPK's activity levels, and then come to some logical training conclusions. Along the way are some takeaways on interpreting and applying mechanistic research.
Our coaches Will and Giancarlo join the podcast to talk through their experience with cramps, and what's been done to attenuate them. We briefly discuss predictors of exercise associated muscle cramps as well as current theories about why they do occur, while most of the episode is spent on practical considerations, and the long list of potential solutions.
Taking enough rest can be intimidating if it's unfamiliar territory. Our resident philosophers of rest Rory and Maeghan join to take a deep dive into the most common reasons we see people being scared of sufficient recovery. We include plenty of practical takeaways for what to expect when resting, how much is too much, building new habits, knowing when you can get back into training, what not to do, and more.
Six of our Empirical Cycling coaches put their heads together to answer your questions on whether mid season breaks will set your fitness back to the dark ages, managing burnout and disappointment, if younger athletes can still overtrain, balancing intensity and volume, work and family stress, being a "good student" as a coached athlete, training habits, and things cyclists put an emphasis on that they shouldn't.
Today we use Rory's recent post event slump to discuss strategies for refocusing and finding motivation again. This is mostly through the lens of goal setting and how to incorporate season planning, fun and unstructured riding, new disciplines, time with friends and family, being flexible, as well as listener questions on realistic goal setting, coping with not meeting goals, training vs racing motivation, and more.
Our very own coach James Mckay sits down to talk about the road to achieving his cycling career goal, a victory at the Lincoln Grand Prix. As this was his last race being coached by Kolie, they take a retrospective look at all the challenges and hard work that went into the last four years of training that made this such an incredible moment: volume, race specific intensity, cramps, heat training, race weight, pressure for results, and the unanticipated way it all came together.
After walking through the general structure and purpose of rest weeks, we break down the decision trees we use to plan rest weeks ahead of time, or what we look for to add them reactively. We also discuss using subjective metrics in rest week planning, plus if and when we wouldn't trust those metrics. Then we answer your listener questions, including mental fatigue, HRV and RHR, skipping rest weeks, accounting for soreness, and more.
We go deep into a couple papers that measure the relative contributions to early VO2max improvements, and the evidence about whether they're more are muscular or cardiac in nature, and what physiological differences there are with more well trained people. Moderate and high intensity training are contrasted, as well as the obvious shortcuts, plus a first-principles approach to alternative mechanisms. We also answer your listener questions on if you can screw up newbie gains, how much is just mental toughness, and more.
While the definition of a junk mile is still debated, we do our best to come up with a definition, analyze it in relation to training adaptations, and what should be done. We touch on volume, intensity, group rides, mental health, fatigue and security blankets, training camps, recovery, hyper-optimization, and lots more.
Our coaches Fabiano and Giancarlo join to discuss the balance between parenting and training, both from a coaching perspective and as parents themselves.

Training focus, rehashing old plans, trying new things, monitoring fitness changes, incorporating fun rides, developing training skills, personalizing your plan, power vs weight, and more, including your listener questions.
Concluding the series on hypoxia inducible factor in skeletal muscle, we go in depth with a paper investigating regulation pathways that blunt HIF's effects in well trained athletes, plus speculate as to whether the Pasteur effect is something worth worrying about while considering other evidence and parallel adaptive pathways. We also ponder some practical takeaways for very well trained endurance athletes as well as for those earlier in their training career.
Our very own Coach Fabiano joins for an deep dive into his most recent articles on RPE and its origins in exercise physiology, workout feedback and what athletes should keep notes on, adaptation and the implications from another meta review as it pertains to well trained athletes and other groups. We then venture into health to discuss VO2max, HRV, the J-shaped curve of training volume, plus your listener questions.
Jem Arnold takes a break from his PhD studies to discuss the implications of a recent meta review and systematic analysis on how training intensity distributions impact VO2max and time trial performance, on which he is a coauthor. We also dig into the methods behind a paper like this, and the statistical distributions of performance itself and how that affects interpretation. We also discuss his doctoral studies on flow limitations in the iliac arteries, the role of NIRS, and long term implications of training with such issues, plus his blog, VO2max training, and more.
As structure for a larger discussion on performance, adaptation, and energy needs, we tackle three myths about burning carbs and fats: that you only need to replace the carbs you burn on a ride, that burning fat on a ride helps you lose weight, and that total energy needs are as simple as converting bike kJ to calories and adding a calculated BMR. We also answer listener questions on efficiency, the origin of the 2000 calorie diet, where your workout carbs go, fueling for ultras, and more.
This episode covers practical cues that we use to be reasonably certain that workouts will have their desired effect, and tease apart the difference relationship between stimulus and adaptation. We give suggestions for the major training modalities including threshold and VO2max, plus strength and hypertrophy. We also discuss ways that these cues could be easily misused, plus the pros and cons of some other potential proxies like fatigue, power, heart rate, RPE, HRV, soreness, TSS, and more.
Our Empirical Cycling coaches have a roundtable discussion on the most under appreciated and impactful big-picture training habits you can make. We discuss progress expectations, goal setting, all or nothing mentality, vicious and virtuous cycles, balancing personal priorities, and many other factors that are within our control to improve. Then we tackle listener questions including improving climbing and low cadence training, high or low "zone 2", what to do about low motivation to ride, fueling early morning riding, and much more.
Finally tackling one of our most requested topics, we discuss the options available for cyclists doing strength training at home with limited or no equipment, and suggestions for cost effective equipment. We go through exercise selection, loading strategies, biomechanical considerations, sets reps and rest schemes, hypertrophy vs strength, sprint power transfer, isometrics, and more. The pros and cons and realities of our suggestions are weighed, a couple thoughts in relation to general health, and many listener questions are answered.
Kolie, Kyle, and Rory go deep into why "the science says" may not be what the science actually says. We discuss the difficulty of the task, the statistical and group-average nature of most results, the fallacy of division, what counts as evidence-based practice, motivations behind clickbait titles and more bullish stances, and where we'd like to see the field of exercise science go in the future.
Billy Ryan of Aware Performance joins to discuss performance psychology. He gives practical guidelines and skills for training and racing, while uncovering their underlying methodology. We cover negative thoughts and feelings around performance, being rigidly flexible, mental focus, confidence vs competence, shaken confidence, and much more. Then we go deep on listener questions.This upload fixes the audio cutoff problem from the previous upload.
Dr. Traci Carson joints to discuss low energy availability and relative energy deficiency in sport, or LEA and RED-S. We consider their origin in the female athlete triad, some differences in female and male physiology and symptoms, the fuzziness of energy intake, symptom overlap with fat loss diets, the need for carbohydrates, the relationship to similar conditions like overtraining syndrome, social considerations and assessing cycling's broader awareness on these issues, and much more.

This episode plays out one of Kolie's coaching thought experiments: what's the simplest training plan possible that would probably be effective for the largest number of people? We each present our plan and then critique them, once again realizing how difficult it is to create a plan without our usual tool of athlete feedback. This starts a discussion about the best potential audience for each plan, the different needs of beginner, intermediate, and advanced athletes.
We discuss everything sweetspot. How do we define it, what kind of training is it, what's the nature of progression, how much is too much, upsides and downsides including time efficiency, fueling, over/unders, and more. We also answer tons of listener questions, like if it can raise FTP, if it's overrated or underrated, sweetspot for sprinters, how long you can hold it relative to your FTP, and much, much more.
A study knocking out HIF1alpha in mice reveals a counterintuitive relationship between markers of phenotype like fat oxidation, mitochondria markers, capillary density, and fiber type, and not having improved baseline performance. This uncovers an interesting relationship between the HIF pathway and oxidative metabolism, and how seemingly opposing adaptations are complementary.

We also answer your listener questions.
This is an in depth discussion on the upsides and downsides of always training to raise FTP vs holding it longer. After defining terms, we discuss the training required, adaptation timelines, fatigue, long term development, plus coaching and event specific considerations. We also consider a few counterpoints for each kind of training, individual response and needs, whether or not this is an actual debate, and answer your listener questions.
This episode goes deep into the integral role that PGC-1ɑ plays in turning exercise signals into aerobic adaptation and improved endurance performance. We then dig into the very surprising results of studies that selectively knock out the PGC-1ɑ gene. Finally, we discuss potential uses of this knowledge for training applications and interpreting the literature, the actual best ways to know if your training (or training "hack") is working, and answering your listener questions.
If you're a cyclist who's intermediate or advanced in strength training, listen in. In our last strength training mistakes episode, we considered more general topics like nutrition, recovery, and periodization. Today we get into issues (and their solutions) concerning how you know you're working the right muscles, using lifting equipment like belts and shoes, range of motion and partial depth, HIT classes and kettlebell swings, power development in the gym, and long term strength goals. We also answer your listener questions that were asked on Kolie's Instagram, like if your knees can go past your toes, if strength training can increase your FTP, where you can see diminishing returns on the bike, going for PRs, and lots more.
By popular demand, we bring you the track episode!

And finally, we answer your listener questions on training for the track.
To kick off 2024, Kolie and Rory discuss how and why training zones fall short, and how they can actually impair progress if taken to logical extremes. We build the conversation back up by thinking about their inception as descriptive rather than prescriptive, how WKO5's iLevels do, the reality of muscular adaptation, and how we actually think about training effectiveness, progression and adaptation.
After you've built up your aerobic engine, what does it mean to get ready to race? Empirical Cycling coach Alex Carmona brings his wealth of coaching and racing experience when discussing transitioning from your build to harder efforts, honing non-fitness skills, the balance of racing and workout intensity in season, and race specific preparation examples. We also discuss tapering into one day races, stage races, high and low volume tapering, guidelines about how often it should be done per year, and as always, your listener questions.
After some background information on what redox state means for exercise and your mitochondria, we look at some experiments linking various intensities of exercise to adaptations. Then we look at where these signals overlap with dieting and rest, and tie these into advice and realistic expectations for training, recovery, and nutrition. We also answer your listener questions on RED-S, measuring recovery, exercise intensity, and more.
This episode looks at all the ways people tend to mess up their rest and recovery days so they're not nearly as restorative as they could be, including such things as riding too hard, lifting weights, cross training, not eating enough. We then suggest guidelines for taking rest days or weeks, getting maximum recovery benefits, individualizing these days to work best for you, and answer your listener questions.
In this episode, 20+ year bike racing veteran Giancarlo Bianchi discusses the tactics of bike racing, and the process of honing racecraft and why people thought his FTP was significantly higher than it is. We cover the chess-game aspects of bike racing like positioning, aerodynamics, wind, reading the competition and body language, course and competitor recon, and a lot of stories from his own race career. We also answer your listener questions like how to practice with few racing opportunities, tactics that might annoy other racers, and much more.

We also answer your listener questions on Legion's tactics, the most important power durations for domestic US racing, racing the course vs racing the people, training regrets, how much pros train, and more.
This is a wide ranging conversation with professional cyclist and Empirical Cycling coach Maeghan Easler. We discuss her successful race season domestically and with the national team, American vs European racing, and how improving fitness changed her training needs, along with more training and coaching topics like volume, recovery, intensity, nutrition and bodyweight, individualizing, and why she prefers 7 hour rides to 8. Instead of listener questions to finish the episode, we react to your controversial training takes submitted for a now forever-lost episode.
This episode takes a long look at the mechanisms behind aerobic adaptations from high intensity exercise, starting with an early study showing how AMPK activation leads directly to mitochondrial biogenesis, followed by a recent meta-analysis showing when high intensity exercise does and doesn't lead to adaptation. We provide guidelines in terms of exercise intensity, duration, and how well trained you are. Then we give some practical takeaways, plus debunk all the ways "hacking" this adaptive signal chain don't work. Marinus Petersen of KiloWatt Coaching steps in as a guest co-host for Kyle and provides an additional perspective from his coaching experience, and his formal exercise physiology education.

To celebrate a half million podcast listens, we roast some of the earliest training plans Kolie wrote almost a decade ago. We get into lessons learned and how the coaching has changed, changing training fads, working with natural talents, and listener questions on "the science", impactful events, and advice for new coaches.
Cycling meme Hall of Famer Feedzone News joins the podcast to announce a new research division. We discuss the first three research papers and all the shortcuts you can use to go faster. Thanks to all of our new podcast sponsors!
This is a conversation between Kolie and epidemiologist Dr. Traci Carson, RDN and cycling coach Dr. Namrita Brooke, and MD and cycling coach Dr. Fabiano Araujo, in light of the Kristen Faulkner disqualification at Strade Bianche for wearing a continuous glucose monitor. We look at topics of whether CGMs actually confer a performance advantage, where their true utility lies, their shortcomings, thoughts on the UCI rules and Faulkner's DQ and the role of a team or dietitian, and health issues surrounding endurance athletes like RED-S and LEA.
This episode goes into Kolie's philosophy on programming and structuring over/under workouts. Duration of overs and unders, intensity guidelines, additional manipulation like cadence, how to progress them, and suggestions for disciplines like CX, MTB, crits, and track. We also discuss some alternative workouts to achieve some of the same touted benefits of over/unders such as better buffering capacity, and your listener questions.
The host of benefits associated with over-under workouts includes improved lactate oxidation and clearance capacity, great expression of MCT enzymes, as well as improved tolerance of associated metabolic byproducts over threshold. We look at the established mechanisms behind these phenomena and find that over-unders, as well as lactate presence and oxidation itself, probably don't have a unique adaptation unavailable to other types of training. The follow-up episode, Ten Minute Tips #27, will discuss how Kolie views and programs over-under workouts, as well as alternative workouts to achieve the same ultimate effects.
This is an in-depth discussion on weight loss diets for endurance athletes, with Dr. Namrita Brooke. The conversation includes guidelines on finding your starting point and how to adjust energy intake, avoiding crash diets, performance expectations and markers when dieting, the effect of off-bike activity, and reasonable loss rates. We also discuss energy balance vs hormones, demonizing food groups and the role of each macronutrient, the best times of year to lose weight, and your listener questions on diet aids, recomp diets, calorie estimates from wearables, finding a good performance dietitian, and more.
This episode is a coaching perspective on the upsides and downsides of when you just want to "set it and forget it." We cover pacing adjustments, mental state, fatigue and threshold feedback, and putting the "max" in VO2max intervals. Plus a couple scenarios where erg mode is an excellent tool.
Dr. Patrick Smith and Kolie sit down to discuss the athletic and coaching implications of Karl Friston's free energy principle of the brain, the right approach to bridge the gap between expectations and observable reality in training, and the right amount of sensitivity to this feedback. This dovetails with the appeal of quick fixes, miracle intervals, and silver bullet training principles. We also discuss what practical solutions are, setting yourself up for success, and your listener questions.
This episode investigates the scientific relationship between size and power (allometry), both vo2max and maximal strength and power, and what it can teach us about sound training methods. How do w/kg and w/CdA scale? Why can't gaining muscle add aerobic power? Why can FTP seem to drop when dieting? Why do we rebound from crash diets? Why do most Tour de France winners seem to fit a certain size and weight? We answer all these questions and more, plus your listener questions.
Does overtraining cause mitochondria to dysfunction? We look at data in the Flockhart study on excessive training and compare them to the headlines, a similar overtraining study using proteomics, and a published response to Flockhart. We break down mitochondrial function, what various measurement methods actually tell us, why your mitochondria are probably just fine, and why these studies raise more questions about mitochondria's role in overtraining (if any) than they answer. Finally, we answer your listener questions on the Flockhart study, mitochondrial function, and overtraining.
Kolie sits down with Cory Lockwood to discuss breaking the U.S. 40km ITT record, going under 45 minutes. Cory also talks about what's different working with Kolie from previous training he's done, along with observations about rest, FTP and VO2max training, training during race season, and reflections on what it means to be both an athlete and coach.
This episode answers the question: is there something unique about endurance riding that is unavailable at other intensities? After discussing "zone 2" definitions, we look at adaptations and dose relative to other training intensities, fatigue, and volume. We look at the relative necessity of endurance riding in both very low and high volume training, and answer listener questions, including if there's a lower limit for endurance pace.
Master coach and WKO5 product leader Tim Cusick joins the podcast to get his brain thoroughly picked. Training topics include the biggest differences between average cyclists and the top pros, the usual periodization schemes vs Olympic cycles, the evolutionary process of a training plan, expertise vs mastery, and of course, resting.Data topics include whether we'll ever get the AI coach in our lifetimes and what it might do when it's here, what WKO5 is and isn't, the secrets of the PD model and mFTP, the PMC, TSS, training impact score, and the value of lab testing.Tim also answers listener questions about how he prescribes training targets, low cadence training, youth development, and advice to get the most out of a coaching relationship.
To celebrate 400,000 podcast listens, we answer your questions submitted in the Empirical Cycling Instagram stories. We discuss high and low volume training and progressive overload, 3 things every cyclist should do, low CHO training, FRC for mountain bikers, supplements for athletes, our best non-empirical cycling advice, and much more. The full questions list is available on the website.
This episode breaks down the origins of endurance performance and how cells control substrate oxidation. We review a paper looking at the difference in adaptive aerobic signals when participants used significantly different amounts of fat and carbs at the same intensity. We then look at the role of mitochondria in cellular energetics, the pivotal role they play in aerobic endurance adaptations, and finally what the training implications are. Plus we answer your listener questions submitted to Kolie's Instagram.
Are you a CTL junkie? Terrified of letting it drop? Listen in. This episode takes a critical but realistic look at TSS and the metrics it's built on like CTL, ATL, and TSB. We discuss normalized power, what kind of fitness CTL can actually reflect, and answer listener questions.
Andy Coggan joins the podcast again to discuss everything we didn't get to in the previous episode. We get back stories behind the adaptations by training zones chart and the category and w/kg chart. We also go in depth with nitrate supplementation, vo2max training. if burning fat makes you burn more fat, if signaling studies translate to performance, and the nature of adaptation itself. There are plenty of pithy proverbs along the way.
In this episode, Andy Coggan discusses FTP and its context among various threshold definitions, the infamous "hour of power", and the legacy of Training And Racing With A Power Meter. We also discuss Andy's lack of social media presence, the chapters he's written on the history of exercise physiology, and delve into some topics in exercise metabolism including VLamax, substrate use at FTP, methods and interpretations of the lactate shuttle, and more.
The interviewer becomes the interviewed as the host of That Triathlon Show joins Kolie. Mikael talks about what he takes from all the interviews he does and how they change his approach, multisport training and periodization, podcasting, pacing, and what Mikael's favorite meme is. He also answers your listener questions.
More FTP may be better, but not always. This episode explores ideas around how FTP can be overemphasized in training in both the short and long term, leading to suboptimal fitness and race outcomes.
Think your FTP is the power you can hold for 60 minutes? Think again! We dig into a classic Billat paper on time to exhaustion (TTE) and training threshold by adding time in zone. Then we discuss into the metabolic implications of these results, how they align with real world experience, and how this affects training and assessment of its effectiveness. Finally, we answer your questions as asked in Kolie's Instagram stories @empiricalcycling.
Should you always train like you race? In this episode we investigate three myths related to this idea, and find some grains of truth along the way. The myths are 1. Sprinters and non-sprinters really need to train aerobic systems differently. 2. Crit racers mostly need to focus on anaerobic efforts. 3. You won’t need to train FTP if you don't race time trials. We touch on some track sprinting as well, and of course answer listener questions from Kolie's instagram, so follow him there if you'd like to ask a question on the podcast.
Marinus Petersen of Kilowatt Coaching and graduate of Loughborough University joins us in this episode to discuss a recent paper on bias in research, but it of course evolves into much more. We discuss the line between scientific research and real world experience and the usual suspects in a conversation between coaches including lactate, critical power, warmups, and more.
This episode explores how individualization of training is why the answer to almost every question is "It Depends." We discuss a few things like tapering, volume, intensity, recovery, the one instance we could think of where there is a definite answer, and also take listener questions submitted from Kolie's Instagram.
RJ Boergers and Angelo Gingerelli join for a discussion of strength training for endurance cyclists, their book "Finish Strong" as well. The episode is full of practical takeaways and in depth discussion of strength training principles.
We begin our foray into listener-submitted training myths, looking at the largest issues with the claims, and discussing why, as always, it depends.
This episode's myths are: 1. Low cadence riding is strength training. 2. Burning more fat makes you better at burning fat. 3. You should do your base rides in the little ring.
Please reach out if you'd like to submit a training myth!
While the phosphocreatine energy system is well known for sprinting, it also has another crucial role as part of the aerobic energy system. We delve into creatine's part in not only temporal energy buffering, but spatial too, and how cells are organized to support this and how badly organisms suffer without it. Then we look at more research showing that the aerobic recovery of phosphocreatine is highly correlated with repeated sprint power, and come to some practical conclusions we can make from the research.

The episode concludes with some tips to help recognize and avoid overtraining, along with listener questions.
This discussion with Namrita centers on ride food questions like how much, when, how to adjust for early rides, races, and if protein and fat is necessary. Additional side quests include the glucose-fructose ratio, how important ride food is in the context of the day, gastric emptying rate, the effects of caffeine, solid vs liquid food, and many others.
Kolie and Kyle discuss the mental and physical aspects of going into an FTP test and add some perspective on nerves, rest, and softening blows to the ego. Then three alternative RPE or data based, submaximal methods are discussed. We also touch on tests that go too well and how to adjust to realistic numbers for training, and why it's better to be consistent than play whack-a-mole with occasional good days.
CTS coach Adam Pulford shares his thoughts on the ins and outs of recovery and how crucial it is. Topics including signs you need a rest week, how often you should take one, rest week structure, if sprints are okay during a recovery day, and the benefits of apple picking.
In this ground-breaking, tell-all episode, Kolie needles Kyle before he pulls at a thread, and Kyle's yarn untangles the skein of reality and explains how you can use the underlying fabric of the universe to bring your cycling performance to the next level.
Former national time trial champion Cory Lockwood fields questions from Kolie and podcast listeners about the ins and outs of time trialing, including his #1 tip for time trialists of all levels. We cover pacing, gearing and equipment selection, and mental focus. Plus we talk about how Cory's training is going, fueling for big workout days, the team behind a big performance, and the unexpected usefulness of mirrors and plastic wrap. All while his cats try to steal mic time.
Does your training zone determine the fiber type used? Does fiber type determine aerobic or anaerobic pathways, carbs or fats? We answer these questions by looking at evidence and concepts that show that fast twitch fibers can be just as aerobically capable as slow twitch fibers, nearly as good at burning fats, and why that might be. We dissect a paper on elite cross-country skiers, and another paper on whether or not fast twitch fibers had been recruited at relatively low intensity. In-depth discussion follows on fiber type distribution, muscle mass recruitment and force availability, why endurance athletes defy the expected metabolic properties of fast twitch fibers, and why these expectations may have started with cats.
Kolie makes his case that power meters are rendering lactate testing obsolete for most cyclists. After some background about lactate and why lactate testing was (and still is) historically crucial for science, we compare lactate test values in ramp and MLSS tests between individuals from an excellent but under-appreciated study. We also dig deep into more recent data, from the lactate test of a former world champion and Kolie's own surprising MLSS test, and the physiology explaining these results. We conclude with practical considerations about what threshold means, and why power meters are our best way to measure it.
Tim Podlogar, nutritionist for Bora-Hansgrohe and research fellow at the University of Birmingham, joins Kolie for a conversation. Just a few of the topics covered are what makes Slovenian riders so good, what lab tests are useful and for whom, low-carb rides, and why substrate use is not adaptation. Nutrition topics include fructose, "fat loading," the role of supplements like creatine, bicarbonate, and beta-alanine. Also discussed are things like responsibility for our media's influence, and the pressures, dangers, and nuances of MDPI and scientific publication.
This fantastic and nuanced conversation starts with discussing why it can be so hard to rest, but went into much deeper territory with changing one's behavior to better move towards goals. We explore ideas like a coach's job to moderate athlete responses to cultural and social pressure, managing the firehose of data, and the definition of insanity. Also touched on are practical ideas for self-coached athletes, such as leaving workout comments for yourself or daily journaling.
Kolie spent yet another year on Instagram (@empiricalcycling) answering questions in the stories for 51 out of 52 weeks to add a bright interlude to doom scrolling. This podcast contains 32 questions under the topics training intensity, periodization, adaptation, and general. Questions, and timestamps for the headings, can be found in the show notes at empiricalcycling.com.
This episode takes a cue from Kolie's recent webinar on balancing aerobic and anaerobic training (linked in show notes) and delves deeper into the temptations of training to a metric or fitness test. We deconstruct some common FTP tests and metrics like FTP, FRC or W', and VLamax, and their interpretations and over-interpretations. Most of the discussion is about what drives these metrics, the pitfalls therein, and if you're actually getting less fit when they shift.
In another wide ranging discussion, we discuss where the sweetspot vs polarized dichotomy may have come from as a stepping off point to consider if you should use such rules decide your training intensity distribution ahead of time.
Zwift training content manager and Never Going Pro podcast host Shayne Gaffney joins the podcast to discuss his role at Zwift, and what it's like building workouts and training plans for large numbers of unique users. We also cover how he got his start, coaching mistakes and lessons, parenting-cycling balance, and the symbolism in the Zwift logo's one sharp corner.
This conversation explores functional exercises as a continuum from your standard fare squats to the functional variations you might see on Instagram. We discuss if they're viable alternatives to normal training, good resources for functional exercises, and the weirdest ones we've ever seen.
In this episode we look at what fatmax is, where the promise lies, and what validity there is. Do you get better at burning fat by burning more fat? Do you lose more weight by burning more fat? How does e=mc^2 relate to the energy stored in food? This episode answers all these questions and more.
This episode was recorded not to be a traditional podcast, it's a call between Kolie and his client Ingvar Ómarsson who is professionally racing mountain bikes. The 2021 season was our first working together, and we go over what went right and what can be done better, and apply those lessons to the plan for next season.
Kolie and new Empirical Cycling coach Cory sit down for a discussion on previous coaching relationships, cultivating new ones, training and racing experience, and coaching red flags. They also get into Cory's motocross experience, technical aspects of criterium bike setup, and the difficulties of Zwift racing while living in a car.
This episode takes a bird's eye view on periodizing strength training in your season including adaptation, hypertrophy, strength, maintenance if needed, and even more specific periodization suggestions for lifting into the season. How and when one might plan these phases, how long they would last, and other tangents such as single leg specific phases, deadlift choice, and a bonus rant on whether or not you should do plyometrics for cycling.

Topics touched on are gym basics, the importance of technique, weight progression, range of motion, functional training, RPE, 1 rep max testing, and easy gym days (deloading).
Patrick Smith joins Kolie for a conversation about how to not accidentally rickroll yourself. Included are the usefulness of rigid rules in training and racing, goals vs. values, dealing with disappointment, and why common psychological evaluations don't work with athletes.
In this episode Kolie asks Empirical Cycling coach Alex Carmona and coach Taylor Warren about their first full season racing USA Crits. We discuss highs and lows, the importance of cornering and positioning, and working up the USA Crits team pecking order. Alex and Taylor also put on their coach hats and go in depth about managing fitness and fatigue in a season, having a "fitness reservoir," hot takes on warmups, and tire widths and pressures.
We look deeper into how the body chooses to use carbohydrates and fats, and specifically when and how carbohydrates inhibit fat oxidation. This serves as a jumping off point to take a critical look at VLamax and how it may, or may not, affect your FTP.
What does it really mean to burn something aerobically? This episode concludes the first phase of this series by looking at both the Krebs cycle and the electron transport chain, and putting them in perspective. In what way is burning fats or carbs aerobic, and how aerobically different are they from each other?
In this episode we answer questions asked on Instagram and r/velo. The podcast isn't dead!

This episode revisits FTP testing. We look at the progressions outlined in the 2018 FTP testing article, intensity domains, FTP, heart rate, and critical power, ramp tests, and defining terms in the sciences. We also look at "training ruts" and their effects on open-ended FTP tests, and methods to avoid those ruts. The podcast concludes with discussing definitions of various thresholds in the scientific literature.
In this episode we discuss preparations for successfully Everesting. With training we discuss periodization, cadence, and bike fit, and logistic preparations include picking the right road, nutrition, gearing, and dealing with mechanical and accident risks.
We answer your questions from the last episode on VO2max training, and, also at listener request, we look at some of last episode's Rønnestad material that got cut out.
VO2max questions include: Aspects of position like standing and TT bikes. Transfer of heart adaptations to normal cadence riding. The right cadence, pacing, and terrain for intervals, rest intervals. How Kolie would structure VO2max training for thousands of cyclists at a time. What 30/15s (and other intermittent intervals) do better than raise VO2max. Periodizing VO2max through a season. What does it take to make your training adaptations your "new normal"?
This episode is the focal point of the previous VO2max episodes. We take the physiology from the previous episodes and use it to find easy ways to improve the effectiveness of any VO2max interval set. Ways to change your cadence, interval times, rest times, and interval intensities are discussed. Then we take apart a Ronnestad study on 30/15s and put it in context of VO2max and other fitness adaptations. We conclude with a training philosophy discussion on the physiology of true long term VO2max improvements.
In the penultimate episode of the VO2max series, we dive deep into how the heart pumps and adapts, how this stress leads to increased VO2max, and why cyclists may not want to take training cues from cross-country skiing.
Three collegiate conference directors and a board president walk into a bar... hypothetically. This is what it would sound like if it were at all safe to go to a bar.
We talk about our fall season cancellations, challenges faced by race promoters, predictions for spring 2021, and reactions to rumors of a Zwift nationals. In the discussion are conference directors Nick Luther of SECCC, Kyle Helson of ACCC, Kolie Moore of ECCC, and ACCC board president Laura Ann Leaton.
This episode explores how and why hemoglobin's function emerges from its structure, which makes it a critical component in the oxygen distribution chain. We also discuss the lungs, why VO2max isn't related to hematocrit, and vascular capacity for blood storage before diving into a classic phlebotomy study that ends with a question mark that hints at the central importance of the heart.
Continuing the VO2max series, we take such a close look into the Fick equation we only cover one of its terms: the arterial-venous O2 difference.
We break apart the factors that affect diffusion of oxygen into our muscles, limiters of oxygen utilization, and whether these factors are trainable to potentially improve VO2max.
The slow component of vo2max is often mentioned but seldom discussed. We take a deep dive into the nature of the slow component, including thermodynamics, fiber type, and the size principle.
In the first episode in a VO2max series, we take a deep dive into why VO2max power, or maximal aerobic power (MAP), is not a simple number that can be found in a simple test. We discuss the history, physiological, and methodological underpinnings of ramp tests and what makes them flawed, and what some people have done to try and account for these. Additional methods of MAP testing and tracking and their drawbacks are discussed. We conclude with some practical advice for ways to monitor improvements your own VO2max.
Lactate remains a misunderstood molecule, and most popular experts still don't have a full understanding of where it comes from or why. In this episode, Kolie explains the basic biochemical context of lactate, where it really comes from, and why we make it at rest and during exercise. You will come away from this episode with a good understanding of how enzymes catalyze reactions, the importance of always making lactate, and the kinds of things that cause demand on glycolysis.
Today we discuss the global COVID-19 pandemic. We start with basic virology and why it's through this understanding that we recommend even healthy people take extreme precautions. Then address group rides, and things to consider for your current training or re-planning your 2020 season for races that may or may not happen. We have links to additional studies in the show notes on the website.
We asked for questions, and we got them. Kolie and Kyle answer eleven excellent questions on FTP training.
Delving into the biochemical depths of all life, Kolie discusses chemical equilibrium, or disequilibrium, and how ATP's high energy phosphate bonds aren't really what give it the energetic potential it's known for.
Today Dr. Helson runs the numbers on how much rotating weight matters when accelerating. The answer may (or may not) surprise you.
Whether we should pace endurance rides by heart rate or power is a training question where the usual answers lack sufficient depth. In this episode we provide enough context, and an alternative, that you might find the right style of riding for yourself.
In this highly anticipated episode, a scientific paper and some metabolic logic show us a simple, effective way to make your FTP training better.
This episode takes a look at things like power output and when we might find differences in training response. Most energy systems are touched on along with quick insights that will be expanded on in upcoming podcast episodes.
Are your friends using bro science? Do you know someone with a magic solution, who thinks they put together the whole puzzle with only half the pieces? Learn the warning signs! Kyle hosts this episode on how to recognize bro science, its rhetoric, and typical warning signs.
Oxygen is corrosive, but we need it for life and exercise. This episode looks at how free radicals are made in the body, their role in adaptation to endurance exercise, and the body's natural defense mechanisms.
The episode starts off with a primer on parts of muscle needed for contraction and how these relate to different methods of fiber typing (there's more than one!). We finish our look at a classic paper on cycling physiology and its sections on fiber type and substrate use. Then a paper on cross country skiers throws a bag of monkey wrenches into decades of established fiber type paradigms.
Do companies really make the best hydration mixes? They do, kind of, but they're expensive. It's difficult to adjust their mixes to flavor and your unique needs. This episode goes through a homemade drink mix that will probably hydrate you better, and definitely for cheaper, than anything on the market today. The recipe can be found on the website show notes at http://www.empiricalcycling.com/podcast-episodes/ten-minute-tips-2-homemade-hydration-mix
Kolie and Kyle look at the relationship between FTP and VO2max. We use data from a classic paper that calls into question the validity of a long-standing testing protocol in the scientific literature, which is still in use today.
The last month before your cyclocross season is a crucial one. In the new Ten Minute Tips series, Kolie looks at the elements of training you may want to incorporate to get a strong start to your season. Included are key workout types, how to manage intensity, incorporating running, and mixing technique work into training rides. Includes three example workouts.
We talk to Empirical Cycling athlete Emma Edwards for an in-depth race report about the 2019 Cascade Classic, where she was racing with Amy D Foundation. We talk about her top 10 on the GC, the gods of mechanicals, what it's like racing against TWENTY20, and her bike's gremlin... just don't get it wet, somehow, in the Pacific northwest.
One of the theorized benefits of low carb or ketogenic diets for cyclists is that it spares glycogen so it can be used when needed most. Kolie and Kyle walk through a paper investigating this question. They then discuss the upsides and downsides and potential utility of fat-adaptive diets in daily training.
The podcast's first deep dive into muscle physiology, we look at a study on weight lifting while endurance training vs just endurance training, with a surprising result. From here we talk about the size principle, which you're using a lot more often than you think.
