The GoFit Extreme Ab Wheel will take your abdominal workouts to the next level! Not only can it be used like a regular ab wheel, but you can strap your feet to the wheel to challenge your abs and back in all new ways. The hand grips/pedals are made of soft rubber for superior grip and stability. The pedal straps are velcro and easy to adjust. The oversized wheel has grippy traction for extra stability and performance.
