Cable Crunch

How to do the cable crunch

  1. Kneel below a high pulley that contains a rope attachment.
  2. Grasp cable rope attachment and lower the rope until your hands are placed next to your face.
  3. Flex your hips slightly and allow the weight to hyperextend the lower back. This will be your starting position.
  4. 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.
  5. 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.
  6. Repeat for the recommended amount of repetitions.

Muscles worked

The prime movers are the rectus abdominis and the obliques, which flex the trunk forward and resist it being pulled into extension or twisted out of line.

How this movement works

One joint changes angle and the resistance travels toward you along a single arc. Nothing is positioned to help, so tension stays where you aimed it and the usable load drops sharply against a multi-joint pull for the same muscle. Protect the range of motion; buying weight by shortening the arc defeats the point.

It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.

What you need

A cable holds tension for the whole range, including the point where a free weight would go slack. Moving the pulley changes the angle the resistance arrives from without changing the movement.

Difficulty

Listed at beginner level: the pattern is simple enough to pick up without coaching, and a position that goes wrong mid-set is obvious enough to correct on the next repetition.
