For many people, starting an exercise program is quite safe. However, depending on your age and heart health, you may need to see your doctor before starting a vigorous exercise program.

If you answer "yes" to any one of these questions, talk with your doctor before starting an exercise program.
Do you have a heart problem?
Do you have chest pain or discomfort when you exercise or are active? Do you have this pain even when you are not exercising?
Does your heart often beat too fast or too slow when you are at rest?
Do you become lightheaded, lose your balance, or lose consciousness? Have you fallen more than 2 times in the past year?
Do you have problems with your bones or joints? If so, does it get worse when you exercise? Do your legs or buttocks hurt when you walk?
Do you take medications to treat a heart condition or a blood pressure problem?
Do you have any wounds on your feet? Do these wounds take a long time to heal?
In the past six months, have you lost weight for no clear reason?
Can you think of any reason why you should not get involved in an exercise program?
If you answered "no" to all of these questions and you have no cardiovascular risk factors, a moderate physical activity program should be safe for you. But again, if you are a man over 45 or a woman over 55 and want to do more vigorous exercise, you should check with your doctor before getting started.
