Lever seated crunch

Sit on the leverage machine with your back against the pad and your feet flat on the floor. Grasp the handles or place your hands on the side pads for support. Engage your abs and slowly lean back, allowing the pad to move with you. Once your upper body is at a 45-degree angle, contract your abs and crunch forward, bringing your chest towards your knees. Pause for a moment at the top, then slowly release and return to the starting position. Repeat for the desired number of repetitions.
