How to PROPERLY Cable Crunch to Shape Your Abs (How to Kneeling Cable Abdominal Crunch)

Lying flat

Crunched

Kneel facing the stack, rope handle behind the head. Crunch DOWN by curling the spine - ribs to pelvis. Elbows drive toward thighs. Hips stay still.

Common mistakes

  • Hinging at the hips - turns into a bow, not a crunch.
  • Pulling with the arms - defeats the whole point.

Where you should feel it

Coach note

If you've been told 'crunches don't work,' it was because they were unloaded. Loaded crunches with full spinal flexion absolutely do.
