In aerobic, or “with oxygen” exercise, your muscles have enough oxygen to produce the energy needed to perform.
Anaerobic “without oxygen” exercise means oxygen demand is greater than oxygen supply and you can't keep up with the energy your body is demanding.Aerobic exercise includes rhythmic activities that use a lot of oxygen and large muscles over a period of time, such as jogging, swimming and riding a bike. Anaerobic exercise, on the other hand, does not use oxygen to generate energy.
