Bosu Ball Crunch

How to perform it

Step-by-step instructions

1. 01Sit on the BOSU and move your hips slightly forward until the dome supports the natural curve of your lower back.
2. 02Plant both feet firmly, place your hands lightly at your temples or across your chest, and relax your neck.
3. 03Extend your upper back over the dome only as far as you can maintain abdominal control.
4. 04Curl your ribs toward your pelvis until your shoulder blades lift, without pulling on your head or driving through your feet.
5. 05Pause briefly, then lower over the BOSU slowly to the supported starting position before repeating.
