Oct 30, 2015. Understanding how the physiology of the body adapts to exercise can help. Learn the unique characteristics of slow- and fast-twitch muscle.
Fast twitch are the muscles which activate very quickly, for a short amount of time, with the power lasting for a second or two. (Think when you punch something, and your arm flexes for only a second as your fist hits the bag, those are your fast twitch muscles). They’re the largest muscles, with the most potential for power, and toning your body.
