There is no denying that exercise is good for you. We know that those who perform a moderate amount of exercise on a regular basis are considerably less likely to suffer from diseases such as diabetes, stroke and heart attack or experience insomnia. Exercise helps older people maintain their independence and is one of the most effective methods of weight management. It is also very important for our psychological health, as it stimulates the release of endorphins, natural pain killing chemicals that can also improve our mood.
