Setup
- Position a flat bench a few feet in front of a cable machine, facing away from the weight stack.
- Attach a rope handle to the high pulley and select a moderate weight.
- Sit on the bench with your back to the machine, grasping the rope ends and pulling them down so your hands are anchored near your ears or upper chest.
- Plant your feet firmly on the floor, shoulder-width apart, to stabilize your lower body.
How to do it
- Exhale and contract your abdominals to curl your torso forward and downward, bringing your elbows toward your mid-thighs.
- Focus on rounding your spine and 'crunching' your ribcage toward your pelvis rather than hinging at the hips.
- Inhale as you slowly return to the upright position, maintaining tension on the abs and avoiding letting the weight stack touch.
- Perform the movement with a controlled tempo, pausing for one second at the point of maximum contraction.
Form checklist
- Keep your hips and lower back glued to the bench; do not lean forward from the waist.
- Ensure your arms remain static; the movement should come from your core, not your triceps or lats pulling the rope.
- Maintain a slight tuck in your chin to keep your neck in a neutral, safe position.
- Avoid using momentum or 'jerking' the weight down.
Pro tips
- To maximize muscle fiber recruitment, imagine trying to touch your sternum to your belly button at the bottom of the rep.
- Focus on a slow eccentric phase (3 seconds) to increase time under tension for better hypertrophy.
Make it harder
- Incorporate a slight torso rotation at the bottom of the movement to increase the demand on the internal and external obliques.
- Perform a 'dead-stop' at the top of each rep to eliminate all momentum before starting the next contraction.
