Introduction

Exercise—physical activity done regularly—is something people can and should do for a lifetime. It helps people feel and function better physically and mentally. It also helps reduce the risk of many disorders. Older age is not a reason to stop exercising. And it should not stop people from starting. In fact, doing regular exercise becomes more important as people age. Exercise can help keep older people active and living independently longer. Exercise can make even the frailest older person stronger and more fit.

Older people may have many concerns about exercising. They may think they are too old to start. They may think they have too many aches and pains. They may fear injury. They may think they have a disorder that prevents them from exercising. However, these obstacles can be overcome. In fact, exercise can reduce them. It can make people feel younger and better. It can lessen some symptoms that may be blamed on aging. And it can help people avoid or delay some disorders.

Older people may worry that they cannot do most exercises. However, almost everyone can become more active and exercise in a way that benefits health. Exercise does not have to mean a structured exercise program. It does not have to include such things as sit-ups, push-ups, or jogging. Exercise can be simple activities such as walking. Increasing the amount of time being active each day can also be a part of exercise. Classic examples are taking the stairs rather than the elevator and walking rather than driving when possible.

Exercise also does not have to involve working up a drenching sweat. Moderate exercise, preferably every day, provides significant health benefits. The key is doing enough moderately active things regularly. Exercise can also be done in small blocks of time. Less vigorous exercise can be done for a longer time. The more exercise (done more vigorously and for a longer time), the greater the benefits. But any exercise is better than none.
