The Cybex Plate-Loaded 45 Degree Leg Press New Style is a leg press machine. A leg press is a machine for working the leg muscles. It is available in 45-degree, seated, or horizontal configurations. The 45 Degree and Seated Leg Presses put the user in front of a large movable foot platform at an angle or upright. Load or select the weight, then place your feet shoulder-width apart on the platform and push it away from your body by extending your knees and hips. A horizontal leg press has a movable carriage with an angled pad, shoulder pads, and a large foot plate. The user lies on their back with their feet shoulder-width apart and lifts the weight by pushing against the plate.
