How many reps of the cable kneeling crunch should a beginner do?

Start with 3 sets of 12 reps at a light weight, holding the forward-hinge starting position steady rather than changing it rep to rep. Add small amounts of weight once your hips stay fixed for every single rep of a set.

What can I do instead of the cable kneeling crunch without a cable stack?

A band anchored high and pulled from the same kneeling, forward-hinged position works as a close substitute. Without either, a bodyweight kneeling crunch against no resistance still trains the same spinal curl, just without progressive load.

What is the cable kneeling crunch good for?

It is a beginner-friendly way to add resistance to ab training since the kneeling base is stable and the load is easy to control. It is a poor choice if loaded spinal flexion bothers your lower back; planks, Pallof presses or carries train the trunk without bending it.

Cable Kneeling Crunch

The cable kneeling crunch loads spinal flexion directly, letting you add progressive resistance to a movement bodyweight crunches soon outgrow. Kneeling below a high pulley with the rope behind your neck, you crunch the ribs toward the pelvis against the cable's steady pull. Because you can dial the weight, it is one of the best abs exercises for building measurable strength.

How to do it

1
Attach a rope to a high pulley and kneel facing the stack.
2
Hold the rope ends beside your head and hinge slightly forward to load the abs.
3
Brace the core and keep the hips still throughout.
4
Exhale and crunch by rounding the spine, pulling the elbows toward the thighs.
5
Squeeze the abs at the bottom of the crunch.
6
Inhale and let the torso rise under control until the abs stretch again.

Tips

Curl the spine to bring the ribs to the pelvis; do not just bow at the hips.
Keep the hips fixed so the abs, not the glutes, move the weight.
Anchor the hands beside the head so the arms do not turn it into a pulldown.

Variations

Common mistakes

The forward hinge that is supposed to preload the abs turns into a hip bend that never straightens back out, so the movement rocks at the hips instead of curling the spine.
Elbows drift wide of the head as the weight gets heavier, turning a spinal curl into an assisted pulldown through the shoulders.
Rushing the exhale at the very bottom of the curl leaves the deepest part of the range under-braced.
Sitting fully back onto the heels between reps releases all core tension and turns a continuous set into a series of restarts.
