Cable Crunch

The cable crunch is the best loaded ab exercise. Unlike most ab exercises, it allows progressive overload — you can add weight consistently. This is what actually builds a defined midsection.

Form Guide

Step-by-step: Cable Crunch

1Kneel in front of the cable, rope attachment at face height.
2Hold the rope behind your head or at your face. Do not use your arms to pull.
3Crunch your ribs toward your hips — not your head toward the floor.
4Key: your hips stay fixed. The movement is only in your trunk.
5Go all the way down to fully shorten the abs, then extend fully to stretch them.

Common Mistakes

What most people get wrong

Pulling with the arms: make the abs do the work, not your lats and arms.
Hips moving: if your hips rock back, you're doing a hip flexion exercise, not a crunch.

Programming

How to program the Cable Crunch

3–4 sets of 10–15 reps. Treat abs like any other muscle — add weight when the current load becomes easy. 2–3 sessions per week. Combine with an anti-extension exercise (ab wheel) and a rotation exercise for complete core training.
