Anaerobic exercise Anaerobic exercise features high intensity movements performed in a short period of time. It can be used by athletes to promote strength, endurance, speed and power; and is used by body builders to build workout intensity. Muscle energy systems trained using anaerobic exercise develop differently compared to aerobic exercise, leading to greater performance in short duration, high intensity activities, which last from mere seconds to up to about 2 minutes. Energy is drawn from a limited supply of stored muscle glycogen to support this short burst of intense activity. Anaerobic exercises demands more energy than Aerobic exercises.
