How to do the Cable Kneeling Crunch
CoreAbsCableBeginner
The cable kneeling crunch is one of the most effective ways to load the abs through a full range of motion, making every rep count far more than endless bodyweight crunches. Master this movement and you will build the kind of core strength that transfers to every lift in your program.

Step-by-step
- Kneel facing the cable stack, grip the rope attachment at both ends beside your head, and keep your hips locked in place throughout the set.
- Brace your abs and curl your elbows toward your knees, rounding your spine from the top down rather than simply bending at the hips.
- Squeeze hard at the bottom position, holding for one count to ensure the abs are doing the work and not momentum.
- Slowly return to the upright position under full control, feeling the abs lengthen before initiating the next rep.
Common mistakes
- Pulling with the arms instead of the abs: think of your hands as hooks and initiate every rep by contracting your midsection first.
- Sitting back onto your heels during the crunch: keep your hips stacked over your knees so the abs bear the load rather than your hip flexors.
- Using too much weight and losing spinal flexion: reduce the load until you can achieve a full curl of the spine on every single rep.
Pro tip — Focus on shortening the distance between your sternum and your pelvis rather than just moving your elbows downward, this subtle mental shift eliminates hip flexor dominance and maximizes true abdominal recruitment.
