The basics of the Leg Master exercise are very simple but so effective. The Leg Master puts hundreds of lower-body muscles to work in order to raise your body against gravity to the top of the curve formed by the rails. Your complete body weight is raised repeatedly using the side-to-side motion of your legs. It's easy to get started with the use of the progress chart enclosed, and you begin with only 20 repetitions a day. Combine this with a sensible diet and light caloric workout; you can lose weight and tone up at the same time. The leg master folds up and stores away easily in a cupboard or under a bed.
