The ratio of fast to slow twitch fiber in a given muscle is extremely trainable. This just comes down to exposure, which means stimuli and time. The more stimuli you give it, the more time you give it,. Andy: An asymptote exists here. So if you are very untrained in your pretty inactive physically, maybe even take new extreme - like spaceflight or cast for two months -- that movement happens faster.

Andy Galpin is a Professor of Kinesiology at California State University at Fullerton, where he studies muscle adaptation and applies his research to work with professional athletes. In this episode, Andy returns to the podcast and continues the conversation about training for longevity. He examines the training practices of powerlifters, Olympic weightlifters, Strongmen/women, CrossFit athletes, and sprinters in order to extract insights that can be applied to the individual wanting to optimize for longevity. Andy goes into detail about exercise load and repetition, training volume, the importance of learning proper movement patterns, the advantage of working to technical failure instead of the number of reps, and much more. Andy ties the discussion together by providing a hypothetical training plan for an individual wanting to optimize for longevity and offers advice for avoiding injury.
