Want to tone your entire body without buying a space-hogging fitness machine? Turn to the Total Gym XLS, a top-of-the-line device that helps you strengthen and sculpt every major muscle group in your body using a single glide board and a few handy attachments. The Total Gym XLS works by making you lift a percentage of your body weight against gravity, creating a smooth and fluid resistance. As your strength and conditioning improve, you increase the total resistance by boosting the incline, thus increasing the body weight lifted in the exercise. The Total Gym XLS not only works your upper body, but also your lower body, abdominals, and even your cardiovascular system. And by reducing body fat and increasing the proportion of lean muscle mass in your body, the strength training effectively turns up the thermostat so that your body burns calories constantly.
