Exercise Ball Crunch
A crunch performed draped over a stability ball, which lets your spine extend further for a bigger range of motion. The ball supports your back at the bottom and adds a balance element, making it a strong step up from floor crunches.
How to do it
- 1
Sit on the edge of the ball with knees bent and feet flat on the floor.
- 2
Walk out and lay your back over the ball so your spine is gently extended.
- 3
Cross your arms over your chest or place your hands behind your head.
- 4
Contract your abs to curl your ribs toward your belly button, tucking your chin, until your upper back lifts off the ball.
- 5
Lower back onto the ball under control, keeping the ball steady throughout.
