How to perform

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