Crunch alternatives

Cable and machine crunches keep resisted trunk flexion. A reverse crunch curls the pelvis from the other end while keeping the upper body on the floor.

Choose according to whether you need a rib-cage curl or a pelvic curl. External loads, machine paths and moving the pelvis change the exercise and its repetition demand.

Anatomical illustration of a bodyweight floor crunch in two frames, side by side on a white background. Left: a woman lies on her back, knees bent and feet flat on the floor, both arms stretched straight out overhead behind her head. Right: the same woman at the top of the rep, head and shoulder blades curled off the floor and the lower back still down, arms still straight and reaching up past her ears. No equipment is shown. The muscles of the front of the abdomen, running from the ribs down to the waistband, are highlighted in red in both frames; the rest of the musculature is drawn in grey.
What equipment can you use?

Choose everything you have. Some exercises need two items, such as dumbbells and a flat bench. Choose floor space for options without equipment.

    Cable crunch

    You need: Adjustable cable pulley set high + Cable rope attachment + Padded floor mat

    Why it fits
    Keeps trunk flexion while adding adjustable cable resistance.
    What changes
    The linked guide uses one knee on padding beneath a high pulley with a rope beside the head. Curl the ribs toward the pelvis while the hips stay mostly still; choose a new stack load.

    Machine crunch

    You need: Seated abdominal crunch machine

    Why it fits
    Keeps trunk flexion against a selectable machine load.
    What changes
    You sit beneath a padded lever or handles instead of lying on the floor. Adjust the seat and pads, keep the hips seated and avoid pulling mainly with the arms.

  • Two-frame side-view illustration of a man lying on his back with bent knees, then curling his pelvis so his hips lift and his knees travel toward his chest, with the abdominal wall highlighted.

    Similar movement

    Reverse crunch

    You need: Floor space (no equipment)

    Why it fits
    Keeps an abdominal curling action without an external load.
    What changes
    The upper back stays down while the pelvis curls toward the ribs. Bent knees and a small controlled hip lift replace lifting the shoulder blades; avoid swinging the legs.

How we choose replacements

These are curated alternatives, chosen for the movement and the job the exercise does in a workout. A shared muscle group is not enough. Read what changes before choosing: support, range of motion, balance and resistance can all differ. If your goal is to improve a specific lift, alternatives do not replace practice of that lift.
