Medicine Ball Crunch on Stability Ball
The stability ball crunch hugging a medicine ball to the chest; the ball's weight rides on every curl out of the stretch.
How to do it
Setup
Lower back on the stability ball, feet planted wide, the medicine ball held on the chest.
Steps
- Curl the ribs up out of the stretch, the medicine ball still on the chest.
- Keep the waist on the stability ball at the top.
- Lower back over the ball slowly.
Common mistakes
Pressing the medicine ball away to help: it stays on the chest. Stability ball shifting under you: feet wider, slower reps. Dropping into the stretch: lower with control.
Breathing
Exhale on the crunch, inhale on the stretch.
