Lowered weight reduces the heart's load and is beneficial in diabetes. Exercise strengthens your bones. When you exercise, bones and muscles work together. Just as muscles grow stronger when physically stressed, so, too, do bones respond by getting stronger. Exercise also increases bone density, which helps prevent osteoporosis, the condition in which bones lose density, weaken, and become porous and very fragile.
Exercise helps prevent cancer.
Exercise speeds digested food through the colon, denying it the opportunity to sit in one place and ferment and cause irritations that can bloom into cancer.

Exercise enhances your emotional well-being. Most people feel calm and have a sense of well-being after they exercise. Any anxieties they had before exercising are tempered or even gone.
