How to perform
- Adjust seat so knees are bent ~90° and pads rest on chest/shoulders
- Grip handles lightly; keep spine neutral and ribcage down
- Brace your core as if preparing for a cough
- Crunch by bringing ribs toward pelvis; move the machine through your abs, not arms
- Pause briefly at the peak squeeze; avoid pulling with hips or shoulders
- Return slowly to the start with control; don’t let the weight stack slam
- Breathe out as you crunch, inhale as you return
- Start light, 10–15 controlled reps; increase load only if form stays strict
