The body converts food into sugar or glucose, which provides the fuel for exercise. Exercise helps to decrease body fat and increase muscle strength, muscle mass and physical endurance. Exercise is a particular benefit to those with type 2 diabetes because it makes the cells more sensitive to insulin. The result is that blood sugar can be used more efficiently, reducing the level of sugar in the blood. Exercise also improves the functioning of the heart and blood vessels, improves circulation throughout the body and helps to control blood pressure.
Exercise also helps to relieve stress and tension and is related to a feeling of well being.
