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.
