Muscle

Okay, so there are two types of muscle utilized in most workouts; Slow twitch and Fast twitch fibers. Slow twitch fibers are big, and they let you crank out endless reps (these muscles are usually used in superset workouts, whereas fast twitch fibers are small and dense, and they create devestating speed and explosive strength (usually used in Plyometric workouts) And also technically there is a third muscle fiber which is a cross between the other two, it has explosiveness and endless endurance, however there is little to none found in humans but commonly in fish and other animals. Its impossible to change your muscle fibers, but you can find workouts that isolate either slow twitch or quick twitch fibers. Next posts will be on workouts for either of these types of muscle.
