Set-up: Adjust the footplate and shoulder pads to your height. Place your shoulders under the padded supports and lean back against the machine. Keep your chest up and core engaged. Unlock the safety handles once in position.
Lift: Grip the side handles for support, then push through your heels to extend your legs. Lower yourself by bending your knees, keeping your back against the pad. Descend until your thighs are parallel to the foot platform (or slightly below if mobility allows). Push through your heels to drive back up to the starting position. After the last rep, re-engage the safety lock before stepping out of the machine.
