Place your desired amount of weight on the bar, equally balanced between the two sides. Position the bar at upper-chest height. Step under the bar into the machine, positioning the bar across your shoulders. Grasp the bar on either side, a few inches outside of your shoulders. Walk your feet out slightly in front of the bar and rotate the bar backward to release it from the rails. Push your hips back and bend your knees, lowering your body like you’re sitting in a chair until your thighs are parallel to the ground (or as close as possible). Reverse the motion and press into your heels to return to standing.

Place your desired amount of weight on each side, equally balanced between the two sides. Sit down into the seat, placing your back against the pad and your feet on the platform. Position your feet shoulder-width apart, keeping your knees in line with your toes. Place your head against the pad and grasp the side handles. Turn the handles to release the safety locks. Press the platform away from you to straighten – but not lock out – your knees. Lower down with control, bending your knees to an angle slightly smaller than 90 degrees. Press through your heels to return to the starting point.
