How to perform Rope Crunch
- Kneel 1-2 feet in front of a cable system with a rope attached.
- After selecting an appropriate weight, grasp the rope with both hands reaching overhead. Your torso should be upright in the starting position.
- To begin, flex at the spine, attempting to bring your rib cage to your legs as you pull the cable down.
- Pause at the bottom of the motion, and then slowly return to the starting position.
- These can be done with twists or to the side to hit the obliques.
Muscles worked
- Core (primary): braces the trunk and resists twisting to protect the spine.
Sets & reps by goal
| Goal | Sets × reps | Load | Rest |
|---|---|---|---|
| Strength | 3–5 × 3–5 | Heavy (~85%+) | 2–3 min |
| Hypertrophy | 3–4 × 8–12 | Moderate (~65–75%) | 60–90 s |
| Endurance | 2–3 × 15–20 | Lighter (~50–60%) | 30–45 s |
Pick the row that matches your goal. If you're newer, anchor in the hypertrophy range while you groove the form.
Form tips
- Brace as if about to take a light punch and breathe shallowly — don't hold your breath for the whole set.
- Keep tension on the cable through the whole range — pause before the stack touches down instead of letting it crash.
- Treat every rep the same — a repeatable setup and bar path is what lets you add weight safely over time.
- Control the lowering phase — a 2–3 second descent builds more than dropping the weight.
Common mistakes
- Cranking with the hip flexors or neck instead of moving from the trunk.
- Letting the stack yank the working muscle back at the end of each rep.
- Chasing weight jumps before the current load feels solid on every rep.
