There are many stories of athletes who visualized themselves practicing before going to bed, whether it be a baseball player engaging in a little batting practice or a diver rehearsing their dives.But you’ll often hear discrepancies among their accounts of how and what they visualized. Some describe going over the same skill repeatedly to work out some kinks, while others describe imagining a perfect performance, or playing out a realistic match complete with the inevitable ups and downs.I think there is a time and place for each kind of visualization, and the research suggests that visualization is indeed a valuable complement to physical practice, but what is the “best” way to do mental practice when our priority is learning new repertoire and skills as efficiently as possible?Source
