Before beginning an exercise program, people are encouraged to consult with a physician. The American Heart Association (AHA) particularly urges people who are older, overweight and inactive or have a family history of heart disease to seek medical advice before starting a fitness program. Once cleared by a physician, it will be important to exercise within 70 to 80 percent of one’s maximum heart rate and to take healthy precautions, such as warming up beforehand and cooling down afterward. Exercise is a lifelong habit, and people are encouraged not to rush into it too quickly or too strenuously. Ideally, it will be enjoyable as well as heart-healthy.

An exercise program should not be implemented without a physician’s approval.
