How to do it
- Attach a rope handle to a high pulley on a cable machine.
- Kneel down a few feet away from the machine and grab the rope with both hands.
- Position the rope with hands beside your head, elbows bent.
- Inhale and brace your core. Exhale as you flex your waist, bringing your elbows towards your knees and crunching your abs.
- Keep your hips stationary and focus on using your abdominal muscles to perform the crunch.
- Slowly return to the starting position, extending your abs.
Common mistakes
- Hinging at the hips and sitting back toward the heels shifts the work from the abs onto the hip flexors.
- Pulling the cable down with the arms activates the lats and triceps instead of curling the spine with the abdominals.
- Hyperextending the lower back at the top of each rep places unnecessary compressive strain on the lumbar spine.
Tips
- Keep your hips locked vertically over your knees and focus solely on curling your ribcage down toward your pelvis.
- Anchor your hands firmly against your head so your arms remain stationary and act only as hooks for the rope.
- Pause for a second at the bottom of each repetition while exhaling fully to maximize the abdominal contraction.

Questions
Is the kneeling cable crunch safe for the lower back?
It is generally spine-friendly when hip movement is restricted, but if you experience lower back pain, stop the exercise and consult a specialist.
How can I replicate this exercise at home without a cable machine?
You can mimic the continuous overhead resistance by anchoring a heavy resistance band to a pull-up bar or high door anchor.
