People are committing considerable time and money to individual programs of exercise. Some simply want to get in better shape or stay that way. Others hope to cope with physical deficits caused by illness or aging. All want to have a good time while improving their health rather than letting it deteriorate.

Everywhere, men, women, children and seniors (even people with relatively serious physical disabilities) are involved in fitness programs. They are working out, swimming, jogging, running (or just walking regularly) bicycling, playing tennis, rollerblading, using exercise equipment, training with weights, rock climbing, dancing, doing aerobics, yoga, Tai Chi and engaging in one or more of innumerable other activities for fitness and fun.

Adults and children are engaging in all sorts of individual and team Sports. Interscholastic and league football, basketball, volleyball, hockey, handball are just some of the competitive and recreational sports people pursue. Golf and tennis remain enormously popular and represent two ends of the wide spectrum of exercise options available from sports requiring relatively little physical effort to those that are extremely demanding.
