In Situp Exercise: Bender Ball Mini Ab Ball

The Bender Ball Workout allows you to work your core in ways you can't do with standard crunches or large exercise balls. With a regular crunch on the floor, your motion is limited to going forward, not back. With the Bender Ball, you are able to get extension back and flexion forward, which works your muscles more effectively for faster and better results. What's in the Box?
