Kneeling Cable Crunch
Why it matters
The Kneeling Crunch builds strength and size in your rectus abdominis. As a compound movement, it trains several muscles together and carries over to real-world strength and power.
How to do it
- Set the pulley to the right height, attach the handle, and step back to remove the slack before your first rep.
- Lie on your back with your feet flat and your lower back in a neutral position.
- Take a kneeling position with your hips stacked under your shoulders.
- Set your position and take the slack out of your midsection before you begin.
- Move slowly and deliberately through the working range.
- Pause briefly where your midsection is working hardest.
- Control the return rather than dropping quickly at the end.
- Curl your ribs toward your hips, lifting one vertebra at a time.
Coaching cues
- Move your ribs toward your pelvis rather than yanking on your neck.
- Kneeling narrows your base — squeeze the glute on the down leg to stay steady.
- Move under control — no yanking or rushing the reps.
- Curl your ribs toward your hips rather than pulling with your neck.
- Keep the tension on your midsection, not your hip flexors or lower back.
Watch out for
-
Pulling on the head or neck to get up.
This takes work off the target muscle and reduces what you get from the set.
Instead Rest your hands lightly at your temples and lead with your ribs.
-
Pulling on the neck or head to complete the rep.
Pulling your head does the work your abs should, so your midsection gets less out of it.
Instead Keep your hands light and lead the movement from your midsection.
-
Rushing through reps with momentum.
Momentum does the work your abs should, so the set does less.
Instead Slow each rep down and control both directions.
-
Arching the lower back away from a braced position.
A loose lower back leaks force and takes the work off your abs.
Instead Keep your ribs down and your midsection tight through the whole rep.
-
Letting the cable yank your arm back at the end of the rep.
Giving in to the cable skips the lowering phase, cutting the work in half.
Instead Control the return against the cable tension rather than giving in to it.
The detail
- Tempo
- Move slowly in both directions and avoid using momentum.
- Breathing
- Exhale as you contract, breathe in as you return.
- Range of motion
- Work through a range you can control without your lower back taking over. Take the rectus abdominis through its full working range each rep.
- Setting up
- Set the pulley to the right height, attach the handle, and step back to remove the slack before your first rep.
- If you are new to it
- Reduce the range or leverage until you can control every rep.
- Once it is easy
- Add a pause at the hardest point of the range for extra tension.
