In this episode, I discuss endurance: our ability to perform effort over extended amounts of time. I describe the four kinds of endurance:

Muscular endurance.

Long-duration (single-set) efforts.

The two kinds of high-intensity interval training that can benefit our brain and various systems of our body.

I discuss the fuel systems they each rely on and how to build up your capillary beds in muscle and in the brain to increase oxygen utilization or improve postural endurance. I discuss efficiency of effort, maximizing quality of effort, and the simplest hydration formula. I review how our heart literally gets stronger (as a muscle) when we oxygenate muscles properly and ways to warm up with and improve respiration/breathing. I also discuss motivation for long bouts of work and the visual physiological basis of the "extra gear" we all can leverage for effort. Finally, I review how accelerating as we fatigue can allow us to access untapped energetic resources. As always, both science, mechanism and tools are discussed throughout
