Kneeling under a high pulley with the rope held behind your head lets you load spinal flexion from a selectorized stack, which is the main reason to pick it over floor crunches once bodyweight sets pass twenty reps. Curl ribs toward pelvis while the hips stay put; if the whole torso drops, it has become a hip hinge.

How to do the Kneeling Cable Crunch

  1. Attach a rope handle to a high pulley and kneel down facing away from the machine.
  2. Hold the rope handle with both hands and place it behind your head, keeping your elbows out to the sides.
  3. Keeping your hips stationary, flex your waist and crunch your torso down towards your thighs.
  4. Pause for a moment at the bottom, then slowly return to the starting position.
  5. Repeat for the desired number of repetitions.

Tip: Breathe out as you crunch and let the last bit of air leave the lungs at the top of each rep.

Muscles worked

Primary

Abs · Core

The rectus abdominis shortens to bend the spine forward, and each rep should end with the upper abs fully contracted and the ribs pulled down.

Secondary

  • Obliques — Twisting or side crunch variations bring the obliques in, and you should feel them along the side of the waist on the working side.

Common mistakes

  • Pulling on the neck — hands behind the head should support, not yank; keep the elbows wide and the chin about a fist away from the chest.
  • Sitting all the way up — a crunch is a curl of the ribs toward the pelvis, not a sit-up; the lower back should stay on the floor the whole time.
  • Cranking out fast reps — momentum does the work if you bounce; lift to a squeeze, hold for a count and lower slowly.
  • Never adding load — once bodyweight reps get easy, hold a plate on the chest or use a cable rather than doing sets of 50.

Where it fits in a workout

Crunches close out a session after the heavy work, or they can fill the rest periods between sets of a lift that does not need much bracing. Pair a cable crunch with a cable side bend on the same stack.

How many sets, how heavy and how hard: see what the ACSM position stands support.

Variations and alternatives

When to talk to someone

  • Chest discomfort, feeling faint or lightheaded, or trouble breathing during or after exercise can be signs of a heart attack. In the US, call 911 right away; elsewhere, call your local emergency number.
  • Heart, metabolic or kidney disease, or symptoms like these when you are active: talk to your doctor before you start or step up training.
  • Pregnant: ask your obstetric care provider which exercise suits you.
