Exercise guide
Lever Seated Crunch Chest Pad
- Intermediate
- Isolation
- Rep-based
- Waist
This isolation exercise targets the rectus abdominis by providing a fixed path of motion, allowing for heavy, controlled resistance to build core strength and definition. The chest pad ensures the load is distributed across the torso, minimizing hip flexor involvement and focusing the effort on spinal flexion.

Setup
- Adjust the seat height so the machine's pivot point aligns with your natural waistline.
- Sit firmly with your back against the rear pad and place your feet securely on the footrests.
- Position your upper chest against the front pad and grasp the handles lightly to stabilize your upper body.
How to do it
- Exhale as you contract your abs to curl your torso forward, driving the chest pad toward your thighs in a controlled arc.
- Focus on shortening the distance between your ribcage and your pelvis rather than pushing with your arms.
- Inhale as you slowly return to the starting position, stopping just before the weight plates touch to maintain constant tension.
- Maintain a steady 2-1-2 tempo: two seconds to crunch, a one-second squeeze, and two seconds to return.
Form checklist
- Keep your lower back pressed firmly against the seat back throughout the entire range of motion.
- Avoid pulling or pushing with your arms; they should only act as anchors to the pad.
- Lead the movement with your sternum, not your head or neck.
- Ensure the movement comes from spinal flexion (curling the spine) rather than hinging at the hips.
Pro tips
- Visualize your ribcage moving toward your hip bones to maximize the recruitment of the rectus abdominis.
- Pause for a full second at the peak of the contraction to intensify the mind-muscle connection.
Make it harder
- Incorporate a 3-second isometric hold at the point of maximum contraction.
- Perform a 'dead-stop' at the top of each rep to eliminate momentum and force a more powerful initial contraction.
