Products Description:
The Ab Roller is an exercise aid based on the patented "Accurate Rocker System." The "Accurate Rocker System" was designed to counteract the tendency of your spine to pivot rather than flex during a workout.
According to the creators of the Ab Roller, the spine is different from any other joint in the body. Other joints pivot when during movements, the spine, however, flexes from vertebrae to vertebrae, creating a curve. During traditional sit-ups this curve can become a pivot, stressing your spine. The creators of the Ab Roller claim the device helps your spine follow it natural curve, thus eliminating or lessening painful injuries incurred while exercising.
Ab Roller allows you to perfectly target your abdominals, while supporting your neck and back. You can perform oblique lifts and complete crunches to effectively target your lower and upper abs, and the cushioned headrest helps reduce stress on your neck.
