Why do I need exercise?
Exercise helps you live longer. It improves your mental health, reduces your risk for a large variety of serious diseases, and makes you look and feel better. Yet half of American adults don't get enough exercise and one-fourth don't exercise at all.
People who engage in regular physical activity can live longer lives by reducing their risks of dying from strokes, colon cancer and heart disease. They are hospitalized less, take fewer medications, and have fewer symptoms of anxiety and depression.
Get checked out by your doctor, who will first see if you have some underlying medical condition that needs attention. Then the doctor will most likely endorse your getting up and moving and help you find exercise regimens that will be good for you.
Regular physical activity can:
