Ball Pass
They call this "Ball Pass" because "Super-Simple-But-So-Deep Crunch You Barely Realize You're Doing It" is a mouthful.
Do it:
- Lie on your back holding an exercise ball and lift your feet so your shins are parallel to the floor.
- Lift your head, neck, and shoulders, and place the ball between your legs.
- Now lower your legs and reach your arms back.
- Come back up and grab the ball.
- Continue to pass the ball back and forth from your hands to your legs 10 to 12 times.
