Physical activity contributes to health by reducing the heart rate, decreasing the risk for cardiovascular disease, and reducing the amount of bone loss that is associated with age and osteoporosis. Physical activity also helps the body use calories more efficiently, thereby helping in weight loss and maintenance. It can also increase basal metabolic rate, reduces appetite, and helps in the reduction of body fat.

Flexibility exercise in its simplest form stretches and elongates muscles. Disciplines which incorporate stretching with breath control and meditation include yoga and t'ai chi. The benefits of greater flexibility may go beyond the physical to the improvement of stress reduction and the promotion of a greater sense of well-being.

Exercise can help older people feel better and enjoy life more, even those who think they are too old or too out of shape.

Exercise, such as weightlifting, helps build muscle that is usually lost with age and puts stress on bones which helps keep them strong and healthy.
