Episode 60: Knowing is Half the Battle

I really enjoyed your eye-opening discussion about endurance athletes. I definitely fit the description of the skinny-fat, weak, slow athlete. I will definitely incorporate more strength and speed work during my offseason this winter.

You mentioned that a bigger muscle can store more glycogen. From my basic knowledge of exercise physiology, I understand that muscles are typically enlarged by means of muscle hypertrophy as a result of weight training, and the muscle fibers that grow are primarily fast twitch, type I fibers. Is glycogen stored in fast twitch fibers? Can the body make use of glycogen stored in a fast twitch muscle during an endurance training session or race? To take this to the extreme, could Arnold in his prime store more muscle glycogen than Lance Armstrong?

Thanks for the show, keep up the great work.
