Moderate exercise is safe for most people, but it's always a good idea to talk to a doctor before starting an exercise program. If you answer “yes” to any of the following questions, it is especially important to talk with your doctor before starting an exercise program. He or she may recommend a supervised or restricted program to meet your specific needs.

• Do you have heart trouble?
• Do you have pains in your heart or chest?
• Do you have high blood pressure?
• Do you ever feel faint or have dizzy spells?
• Do you have arthritis or other bone or joint problems that could limit your physical activities?
• Do you have diabetes? (Increased exercise affects your insulin needs.)
• Do you have two or more risk factors for heart disease? Risk factors include high cholesterol, high blood pressure, smoking, diabetes, and a family history of early coronary artery disease.
• Are you age 65 or older and not used to exercise?
