The original Bender Ball™
 
The Bender Ball allows you to work your core in ways you can’t do with standard crunches or large exercise balls. It has been documented with the Journal of Applied Research and studies have shown that by utilizing the Bender Ball it will generate 4 times the work in an abdominal crunch per each second of exercise.
