Cable Crunch exercise
The cable crunch is a resistance exercise that targets the abdominal muscles, particularly the rectus abdominis. Performed with a cable machine, it provides consistent tension and is highly effective for building core strength and definition.

How to perform Cable Crunch
- Attach a rope to the high pulley of a cable machine.
- Kneel down facing the machine and grasp the rope handles with both hands.
- Hold the rope behind your head or at shoulder level, keeping your hands close to your ears.
- Contract your abs and curl your torso down toward your knees, keeping your hips stationary.
- Pause and squeeze your abs at the bottom of the movement.
- Slowly return to the starting position with control.
- Repeat for the desired number of reps, maintaining core engagement throughout.
What is Cable Crunch?
The cable crunch is a kneeling weighted abdominal exercise performed with a high pulley. The rib cage curls toward the pelvis against cable resistance while the hips stay comparatively still, allowing the abdominal muscles to shorten under load.
What muscles does Cable Crunch work?
The rectus abdominis produces most of the spinal flexion. The obliques and deeper abdominal muscles assist and stabilize, while the hip flexors, lats, arms, glutes, and spinal muscles help hold the kneeling setup and rope position.
Cable Crunch form cues and common mistakes
- Attach a rope to a high pulley, kneel far enough away for steady cable tension, and hold the ends beside the head without pulling on the neck.
- Set the hips over or slightly behind the knees, brace the glutes lightly, and keep that hip position nearly unchanged throughout the repetition.
- Exhale and bring the ribs toward the pelvis by curling the upper and middle spine instead of simply folding at the hips.
- Pause briefly in the shortened position, then return under control until the abs lengthen without letting the weight stack slam or pull the torso upright.
- Reduce the load or range if the movement becomes a lat pulldown or hip hinge, and stop for sharp neck, back, hip, knee, or abdominal pain.
How to add Cable Crunch to a workout
Use cable crunches as a loaded core accessory for 2 to 4 sets of 8 to 15 controlled repetitions, leaving 2 to 3 reps in reserve. Add repetitions before increasing the stack, and keep the same hip position and curling range as the load rises.
Frequently asked questions
What muscles do cable crunches work?
Cable crunches primarily train the rectus abdominis. The obliques and deep core assist, while the hip flexors, lats, arms, glutes, and spinal muscles stabilize the kneeling position.
Should the hips move during a cable crunch?
A small natural adjustment is fine, but the hips should stay mostly fixed. Repeatedly sitting back and driving forward turns the exercise into more of a hip movement and reduces the abdominal curl.
Where should I hold the rope for cable crunches?
Hold the rope ends beside the temples, ears, or shoulders with the hands relaxed. Keep the position consistent and avoid using the arms to pull the head or neck downward.
Use controlled movement and an appropriate variation for your current ability. Stop if an exercise causes sharp pain, and seek qualified guidance when needed.
