Any successful programme whether it’s for fat loss, lean muscle toning or simply keeping fit usually requires some form of increased activity and exercise. This could come in many different forms and could include activity from gym workouts, home circuits, fitness classes or other forms where you are simply doing something active such as stair climbing or hill-walking. Exercise stimulates your body which forces it to adapt to changes which will help you look fitter on the outside as well as having more energy naturally on the inside
