Cable Seated Crunch
The cable seated crunch has you sit on a bench facing a high pulley, hold a rope near your shoulders, and crunch your torso forward and down against the cable's resistance. It trains the same spinal flexion as a floor crunch but from a seated position, and it suits anyone who wants a cable ab exercise without kneeling on the floor.
Why it works
Your abs round your spine forward the same way whether you sit on a bench or lie on the floor, so the seated cable crunch loads that same flexion pattern while keeping your hips fixed by the seat, which limits the temptation to substitute hip movement for spinal flexion. The cable adds resistance you can increase over time, something a plain seated crunch without a machine can't offer.
Set up
- Sit on a bench positioned facing a high pulley with a rope attachment.
- Hold the rope ends near your shoulders and sit up tall with your feet planted on the floor.
- Choose a load that lets you complete the full range with control.
How to do it
- Crunch your torso forward and down, bringing your chest toward your thighs.
- Pause briefly at the bottom of the crunch.
- Uncurl your spine back up to the starting seated position under control.
- Repeat for the set, keeping your hips planted on the bench throughout.
Form cues
- Round your spine forward, don't just tip your torso from the hips.
- Keep the rope close to your shoulders instead of letting it drift away from your body.
- Exhale hard as you crunch down to help engage your abs.
- Keep your hips fixed on the bench, only your spine should move.
Breathing: Exhale forcefully as you crunch down, inhale as you uncurl back to the starting position.
Common mistakes
Bending forward from the hips like a hinge instead of rounding the spine.
Fix: Focus on curling your ribcage down toward your hips rather than folding at the waist.
Pulling the rope down with your arms instead of crunching with your abs.
Fix: Keep your arms fixed near your shoulders and let your torso do the work of pulling the rope down.
Rushing the return and letting the cable snap the torso back up.
Fix: Uncurl slowly under control, resisting the cable the whole way back up.
How to program it
- This is a loaded ab isolation move with a light joint cost, so most people can handle it three times a week without issue.
- Twelve to fifteen reps per set is a solid range, since the goal is a controlled crunch rather than a maximal single effort.
- It works well toward the end of a session, once your abs don't need to stabilize heavier compound lifts anymore.
Safety notes
- Keep the movement in your spine rather than yanking with your neck.
- Choose a load you can control through the full range in both directions.
- Reduce the range if you feel strain in your lower back instead of your abs.

Frequently asked questions
How many sets and reps of cable seated crunches should I do?
Two or three sets of 12 to 15 reps works well, focusing on a controlled crunch rather than moving maximum weight.
What's the difference between a seated cable crunch and a kneeling cable crunch?
Both load the same spinal flexion, but the seated version fixes your hips on a bench, while the kneeling version has you control your hip position yourself, which some people find harder to keep still.
Can I do this without a cable machine?
A bodyweight crunch or a decline crunch on an angled bench train the same spinal flexion without a cable stack.
Why do I feel this in my hip flexors instead of my abs?
That usually means you're hinging forward from your hips instead of rounding your spine. Keep your hips fixed on the bench and focus on curling your ribcage down instead.
