Ab Revolutionizer is an abdominal tool that takes existing and proven abdominal exercises, like the crunch and reverse crunch, and turns them into a super charged exercise. The Ab Revolutionizer works the lower and upper abdominals together. It gives you a full oblique workout; these are the muscles responsible for a flat stomach. The Ab Revolutionizer takes other muscles (back, shoulders) out of the exercise and allows you to isolate and concentrate on the abs. Doing abdominal crunches on the Ab Revolutionizer is a perfect abdominal workout.<br><br>Product includes: Padded Contour Headrest, Instructional and Lynn Brick Training Video, Nutritional Guide, 10-day supply of Nutra Power Bar - Energizing Supplement, 10-day Acceleration Program.
