Exercise therapy is the use of a planned program of exercise designed specifically for an individual's health and fitness needs. It can be a valuable tool to help with one's heart functioning and aerobic fitness. It can take place within the formal setting of a hospital and clinic or can be performed more informally (but just as regularly) at home.

Exercise therapy consists of exercising by walking or running on a treadmill, biking, playing, doing sports activities or lifting weights. Exercise therapy can be done on an individual or group basis.
