Lack of physical activity is a risk factor for heart disease. That’s why it’s important to realize that not only is exercise fun, it’s good for your health.

Physical activity is more than jumping jacks and deep knee bends — it includes any activity from roller skating to dancing. And if you’re fit, you can exercise longer and with less effort than a person who is not in good condition. Physical activity also may be an effective outlet for tension and stress.

Regular physical activity helps you feel better, look good, and can improve your overall sense of well being. It can increase your physical strength and stamina. Proper exercise also can improve your circulation and the performance of your heart and lungs.
