Cable crunch
The cable crunch loads the rectus abdominis without compressing the lower back the way a sit-up does. It is the cleanest loaded ab lift you can do if you do not fancy lying on a mat in a busy gym.

Setup
Attach a rope to a high cable. Kneel a foot back from the stack so the cable runs at roughly a 30 degree angle to vertical. Hold a rope end in each hand and bring the rope down to either side of your face, knuckles in. Brace the abs before the first rep and keep that brace the whole set.
How to do it
-
1
Anchor the hips
Sit back onto your heels so the hips do not move during the rep. Movement happens at the spine, not the hips. If your hips swing, the load is going into the hip flexors not the abs.
-
2
Curl the ribcage down
Pull the ribcage toward the pelvis, rounding the upper back, not folding at the hips. Aim to bring the elbows toward the thighs. Exhale on the way down to fully empty the trunk.
-
3
Pause at the bottom
Hold the squeezed position for one count. This is the half of the rep most lifters skip and the half that actually builds the abs.
-
4
Return under control
Reverse the curl slowly. Resist the cable on the way up. The eccentric is where the muscle does most of its work; do not let it snap back to the start.
Common mistakes
- • Hinging at the hips instead of rounding the spine, which turns the lift into a kneeling row.
- • Pulling with the arms, which works the lats but ignores the abs.
- • Letting the cable yank you back at the top, losing the eccentric.
- • Loading the stack too heavy, which forces the hips to swing.
- • Holding the breath. Exhale on the curl down to squeeze the abs harder.
Variations
Decline crunch
Bodyweight version on a decline bench. No cable needed. A clean home or hotel-gym alternative.
See the decline crunch page →Standing cable crunch
Same lift, performed standing with a rope at face height. Useful if kneeling bothers your knees. Slightly less spinal flexion, slightly more anti-extension.
Dumbbell crunch
Hold a dumbbell across the chest and crunch from the floor. Lower-volume option for home training.
