How to do the Cable Tuck Reverse Crunch
CoreAbsCableBeginner
The cable tuck reverse crunch uses constant cable tension to challenge your abs through the full range of motion in a way bodyweight alone cannot replicate. Master this movement and you build the deep core control that transfers to every lift you do.

Step-by-step
- Attach an ankle strap to the low pulley, secure it around both ankles, and lie flat on your back with your hips close to the cable stack.
- Press your lower back firmly into the floor and bring your knees to a 90-degree tabletop position as your starting point.
- Exhale sharply and curl your pelvis off the floor, drawing your knees toward your chest in a controlled tuck while the cable resists the movement.
- Slowly lower your hips back to the floor under tension, stopping before your lower back arches, then repeat.
Common mistakes
- Using hip flexors to swing the legs instead of curling the pelvis — fix this by focusing on tilting your tailbone toward the ceiling before your knees move.
- Choosing too much weight and losing spinal contact with the floor — reduce the load until you can keep your lower back grounded throughout every rep.
- Rushing the lowering phase and letting the cable pull you down — control the descent for a full 2 to 3 seconds to maximize time under tension.
Pro tip — At the top of each rep pause for one full second and think about pulling your belly button down toward the floor while your knees are tucked in — this brief isometric contraction recruits the deep transverse abdominis and turns a simple crunch into a complete core exercise.
