Developed by master trainer Leslee Bender, the secret to great results is the Bender Method of Core Training. Each of Leslee's ab sculpting moves puts you in the perfect position for results. Combined with her effective method of selective stabilization, it cranks up the intensity and targets the muscles you want from all sides - your upper abs, the sides and those hard to reach lower abs.
What you're seeing in the gym are people doing a gazillion crunches and they don't know why they're not getting results. With a regular crunch on the floor, you're limited. You can only go forward, you can't go back. With the Bender Ball, you're getting extension back and flexion forward, which works your muscles more effectively and gives you a workout that's up to 408% more effective than ordinary crunches!
