Rope Crunch
Muscles worked
Instructions
- 1Kneel 1-2 feet in front of a cable system with a rope attached.
- 2After selecting an appropriate weight, grasp the rope with both hands reaching overhead. Your torso should be upright in the starting position.
- 3To begin, flex at the spine, attempting to bring your rib cage to your legs as you pull the cable down.
- 4Pause at the bottom of the motion, and then slowly return to the starting position.
- 5These can be done with twists or to the side to hit the obliques.

About Rope Crunch
The rope crunch, often called a cable crunch, adds progressive resistance to trunk flexion, letting you increase the load over time, something a bodyweight crunch can't offer past a certain point. Kneeling under a high pulley with the rope held behind the neck, you flex the spine vertebra by vertebra to bring the ribcage toward the thighs, keeping the hips fixed to isolate the rectus abdominis rather than the hip flexors. It's one of the best exercises for continuing to progressively overload the abs just like any other muscle group. A rotational or side variation also lets you target the obliques more directly.

- check_circleThe kneeling position limits hip flexor involvement
- check_circleA rotational variation is possible to target the obliques
lightbulbExecution tips
- lightbulbFlex the spine vertebra by vertebra rather than pulling with the arms
- lightbulbKeep the hips fixed, only the upper back should move
- lightbulbDrive the elbows toward the thighs while exhaling hard
- lightbulbControl the return over 2-3 seconds to keep tension
warningCommon mistakes
- warningUsing the arms as a lever instead of flexing the trunk
- warningPulling from the hips, turning it into a hip-flexion movement
- warningUsing too heavy a weight and losing the spinal curl
- warningKeeping the back flat instead of truly rounding the abs
helpFrequently asked questions
How many reps should I do for the rope crunch?expand_more
Aim for 12 to 20 controlled reps; the abs respond well to slightly higher-rep sets.
What if no cable pulley is available?expand_more
The floor crunch or decline crunch reproduce the same trunk-flexion movement.
