#93 Dr. Andy Galpin - The Relationship Between Muscle Morphology & Exercise Performance

In this episode of The Muscle Memoirs Podcast, I am joined by Dr. Andy Galpin to discuss the relationship between muscle fiber type percentage and exercise performance, recovery, and muscle hypertrophy, along with the limitations of training studies. 

Dr. Andy Galpin is an Assistant Professor at California State University, Fullerton with a Ph.D. in Human Bioenergetics from Ball State University. He is the author of the best-selling book Unplugged, and is a high-performance coach and consultant to numerous professional athletes.
