This machine is designed to help you reach your health and fitness goals without any unnecessary pounding or tugging on your body. When you train on the Ultra Glide Plus, you can strengthen, firm, tone, sculpt and shape your muscles from head to toe. During exercise you pump, push and pull your own weight along the gliding rails, improving your heart and lungs and revving up your metabolism so you can burn fat. The machine comes already assembled, and includes the Owner's Manual.
