Better than Standard Crunches
The secret to great Ab results is the Bender Method of Core Training, created by Pilates and Barre Master Trainer Leslee Bender. The Bender Ball allows you to work your abs in extension and flexion with a greater range of motion that a standard crunch. This method of Selective Stabilization is perfect for targeting your upper core, lower abs, side obliques, upper back and lower back.
