Explain the difference between aerobic and anaerobic exercise
assistant
Aerobic exercise is physical exercise that requires the use of oxygen for the body to produce energy. It usually requires a steady and sustained level of exertion and elevates the heart rate. Examples of aerobic exercise include jogging, swimming, brisk walking and biking. 2  Anaerobic exercise, on the other hand, does not require the use of oxygen for the body to generate energy. It is usually a short burst of intense activity that does not require a sustained level of effort and does not raise the heart rate significantly. Examples of anaerobic exercise include sprinting, weightlifting and plyometrics.
