Cable Crunch: How to Do It, Muscles Worked
The Cable Crunch is a beginner-level strength exercise that primarily works the abdominals. It uses cable, and is performed in 6 steps, following the form cues, common mistakes and sets/reps guidance below.
What muscles does the Cable Crunch work?
The Cable Crunch primarily targets the abdominals, with no listed secondary muscles in the dataset. It's classified as a beginner-level strength movement using cable.
What are the most common Cable Crunch mistakes?
- Using momentum to swing through reps instead of moving under control.
- Holding the breath entirely instead of breathing in a controlled way through the brace.
- Pulling on the neck with the hands instead of driving the movement from the abs.
- Letting the lower back arch off the floor or lose its brace during the movement.
How should I program the Cable Crunch — sets, reps and frequency?
As a core-stability exercise, it is usually programmed by 30-60 second holds, or 10-20 controlled reps, for 2-3 sets. It tolerates higher frequency than a heavy compound lift — twice a week for the same muscle group is common. Add difficulty gradually — more load, more distance/time, or better technique — rather than rushing intensity.
What are good Cable Crunch variations and alternatives?
- Ab Crunch Machine — machine, intermediate level, abdominals
- Bent-Knee Hip Raise — bodyweight, beginner level, abdominals

How to do the Cable Crunch, step by step:
- Step 1. Kneel below a high pulley that contains a rope attachment.
- Step 2. Grasp cable rope attachment and lower the rope until your hands are placed next to your face.
- Step 3. Flex your hips slightly and allow the weight to hyperextend the lower back. This will be your starting position.
- Step 4. With the hips stationary, flex the waist as you contract the abs so that the elbows travel towards the middle of the thighs. Exhale as you perform this portion of the movement and hold the contraction for a second.
- Step 5. Slowly return to the starting position as you inhale. Tip: Make sure that you keep constant tension on the abs throughout the movement. Also, do not choose a weight so heavy that the lower back handles the brunt of the work.
- Step 6. Repeat for the recommended amount of repetitions.

Is the Cable Crunch suitable for beginners?
Yes — the dataset lists the Cable Crunch as a beginner-level movement, though anyone new to training should still start with light weight (or no added weight) to learn the pattern first.
What equipment do I need for the Cable Crunch?
A cable. No other equipment is required for the standard version of this movement.
What's the difference between the primary and secondary muscles listed?
Primary muscles (Abdominals) do most of the work and are usually the limiting factor in the set. Secondary muscles assist or stabilize but aren't the main driver of the movement.
