Exercise is any form of physical activity that uses the muscles and joints of the body to keep fit and maintain health. Aerobic exercise is continuous rhythmic activity that increases endurance and uses oxygen more effectively. Anaerobic exercise is strength training (lifting weights), which uses muscles at a high intensity and rate of work for a short period of time.

Physical exercise can be a vital part of a lifelong approach to health and wellness. Its benefits do not simply derive from movement.  Exercise is an outlet for releasing energy and emotion and for experiencing and toning the body. The body’s response to physical activity has numerous positive effects on musculoskeletal, cardiovascular, respiratory, and endocrine systems -- a decreased risk of premature mortality, lowered risks of coronary heart disease, hypertension, colon cancer, and diabetes mellitus. Regular physical activity also improves depressed mood and anxiety, and enhances the ability to perform daily tasks throughout the life span. Scientific data now indicate indisputably that individuals who perform even minimal physical activity have important reductions in chronic disease.
