Cable Crunch
The cable crunch is a kneeling abdominal exercise that uses a cable machine's constant resistance to strengthen the muscles running down the front of your midsection. Unlike floor crunches, the cable keeps tension on your abs through the entire movement — not just at the top. Strong abs support your spine, improve posture, and make everyday tasks like getting up from a chair or carrying groceries noticeably easier.

Form cues
- 01
Kneel on a folded mat or pad directly below the cable pulley to protect your knees.
- 02
Hold the rope handles so your thumbs rest near your temples — keep your hands there the whole set.
- 03
Lean forward slightly from the hips before you start, so your back has a gentle arch — this is your starting position.
- 04
Keep your hips locked in place; the only thing moving is your upper body curling downward.
- 05
Round your upper back and pull your elbows toward your knees, like you're trying to make your ribcage touch your thighs.
- 06
Breathe out slowly as you curl down, and pause for one full second when your elbows are closest to your knees.
- 07
Let the cable pull you back up slowly and with control — don't let it yank you upright.
- 08
Choose a weight light enough that your lower back never has to take over the work.

Common mistakes
Pulling with your arms instead of your abs — if your elbows are moving away from your head, you're using your arms. Keep your hands glued to your temples.
Rocking your hips up and down — your hips should stay still the whole time. If they're moving, reduce the weight.
Rushing through the movement — if you're bouncing at the bottom or snapping upright, slow down and feel the muscles working.
Letting the weight hyperextend your lower back too far at the top — a slight arch is fine, but if you feel strain in your low back, reduce the weight and limit how far back you lean.
Holding your breath — if you notice your face turning red or your neck tightening, exhale on the way down and inhale on the way back up.
Scale it
Easier and harder variations
Easier
Use a very light weight and focus only on the top half of the movement — curl just a few inches down and back up until you build confidence with the motion.
If you're new to cable machines or feel unsure about the full range of motion.
Harder
Pause for three full seconds at the bottom of each rep with your elbows near your knees, then return slowly on a four-count.
When the standard tempo feels easy and you want more challenge without adding weight.
Note
Replace with a seated ab crunch machine, which supports your back and removes the kneeling position entirely.
If kneeling causes knee pain or discomfort, or if you have a hip replacement that limits floor-level positions.
