Cable crunch

You need

How to do it

1. Grab a rope attachment with both hands and have your thumbs facing up.
2. Kneel and position the rope behind your head. Both hands should be close to your neck throughout the exercise.
3. Once in this position, engage your glutes to produce some degree of posterior pelvic tilt and to engage your abs better.
4. Initiate the crunch by inhaling and bringing the rope down and in. Think of the movement as one where you actively crunch and extend your abs instead of having the movement go through your hips.
5. Hold the contraction for a moment, exhale, and extend your abs until your back is in a neutral position.
6. Repeat.
