I want to become more physically active; do I need to see my doctor first?

Being physically active can provide some protection against chronic diseases such as heart disease, adult-onset diabetes, arthritis, hypertension, certain cancers and osteoporosis. It also contributes to increased bone strength, decreased blood pressure, better sleep, increased "good" cholesterol, increased metabolism and better resistance to colds. To put it simply, physical activity is one of the best things you can do for your self. For most people moderate physical activity is not a health hazard. However talk to your doctor before beginning if you have existing heart trouble, chest pain, diabetes, high blood pressure, your often feel dizzy or faint, or you have arthritis or some other bone or joint problem that might be aggravated by improper exercise. If you are not sure if you have any of these conditions or you have any concerns about the safety of starting an exercise program, give your health care provider a call.
