Instructions
How to do Cable Crunch
Keep the setup simple, use a controlled pace, and repeat the same movement pattern each rep.
- Kneel below a high pulley that contains a rope attachment.
- Grasp cable rope attachment and lower the rope until your hands are placed next to your face.
- Flex your hips slightly and allow the weight to hyperextend the lower back. This will be your starting position.
- With the hips stationary, flex the waist as you contract the abs so that the elbows travel towards the middle of the thighs. Exhale as you perform this portion of the movement and hold the contraction for a second.
- Slowly return to the starting position as you inhale. Tip: Make sure that you keep constant tension on the abs throughout the movement. Also, do not choose a weight so heavy that the lower back handles the brunt of the work.
- Repeat for the recommended amount of repetitions.
Benefits
- Builds strength and control through the core region.
- Makes it easier to focus on one area when you want extra practice or volume.
- Gives you a repeatable way to track progress inside Logbook over time.
Common mistakes
- Using more weight or speed than you can control cleanly.
- Cutting the range of motion short and rushing through the reps.
- Changing your body position between reps instead of keeping the movement repeatable.
