What is Anaerobic Exercise?
While “aerobic” means “with oxygen,” anaerobic means “without air" or "without oxygen." Anaerobic exercise is short-lasting, high-intensity activity, where your body’s demand for oxygen exceeds the oxygen supply available. Anaerobic exercise relies on energy sources that are stored in the muscles and, unlike aerobic exercise, is not dependent on oxygen from (breathing) the air. Examples of anaerobic exercise include: heavy weight-lifting, all types of sprints (running, biking, etc.), jumping rope, hill climbing, interval training, isometrics, or any rapid burst of hard exercise.
