Anaerobic Threshold

The anaerobic threshold occurs during exercise and is the point at which your muscles are using more oxygen than your heart and lungs can deliver. When you reach the anaerobic threshold you generally feel tired, short of breath, and your heartbeat is rapid. Be sure to CONSULT YOUR PHYSICIAN to be sure it's safe for you to exercise to this level.

The anaerobic threshold generally occurs at 80 to 85 percent of your maximum heart rate.
