How to do the Cable Crunch

Cues reviewed by Kwabena Osei on

Setup

Kneeling facing a high pulley, rope handle held at either side of your head, hips stacked over your knees.

  1. Flex your spine, curling your elbows down toward your hips/thighs -- keep your hips still, this is a spinal-flexion movement, not a hip-hinge.

  2. Squeeze at the bottom, then return under control to a full stretch.

Common mistakes

  • Hinging at the hips instead of flexing the spine -- this turns the crunch into a good-morning-style movement and takes tension off the abs.

  • Using your arms to pull the rope down instead of curling with your trunk.
