Why the bosu ball? “By adding an unstable surface, a BOSU ball increases activation of the rectus abdominus and facilitates extra activity per exercise than a stable surface would,” says Meaghan.
3 sets / 12-15 reps
1. Begin by lying on the Bosu ball with your hips just off the edge of the ball. Place your hands behind your head to gently support your neck.
2. Exhale and curl your upper body over the Bosu ball. Hold for a brief second at the top before slowly returning to the starting position.
