Cable Reverse Crunch
- Intermediate
- Compound
- Rep-based
- Waist
The Cable Reverse Crunch adds constant tension to the lower abdominals and obliques, providing a more intense stimulus than the bodyweight version by resisting the eccentric phase. It is highly effective for developing pelvic control and strengthening the deep core stabilizers.

Setup
- Attach ankle straps to a low cable pulley and secure them to your ankles, or hook your feet into a rope attachment.
- Lie on your back on a mat facing away from the cable machine.
- Grasp a heavy object or the base of the cable machine behind your head to anchor your upper body.
- Position yourself far enough away so that there is tension on the cable when your knees are bent at 90 degrees.
How to do it
- Exhale and pull your knees toward your chest, focusing on curling your pelvis off the floor toward your ribcage.
- Hold the peak contraction for one second, squeezing your lower abdominals tightly.
- Inhale as you slowly lower your hips back to the floor and return your legs to the starting position.
- Maintain a controlled 2-1-2 tempo, ensuring the weight stack does not touch down between reps.
Form checklist
- Keep your lower back pressed firmly into the floor as you extend your legs.
- Initiate the movement by tilting the pelvis, not by swinging the legs.
- Ensure your shoulder blades stay grounded and your neck remains relaxed.
- Avoid using your hip flexors to yank the weight; focus on the abdominal 'crunch' sensation.
Pro tips
- To maximize lower ab recruitment, focus on the 'posterior pelvic tilt'—think about pulling your belly button toward your spine before you lift your hips.
- Keep your knees tucked close to your torso throughout the movement to shift the load from the hip flexors to the rectus abdominis.
Make it harder
- Perform the exercise on a flat bench to allow your legs to drop slightly lower than hip level for a greater stretch.
- Slow down the eccentric (lowering) phase to 4 seconds to increase time under tension.
