The Body-Solid Tools Ab Wheel is the perfect tool to strengthen and tone your abs, shoulders, arms, and back. Ab roller exercises force you to isolate the stomach and oblique muscles while you workout. Holding planks has never been more challenging while stabilizing the ab wheel. The Ab Roller features two wheels for added stability and comfortable plastic grip handles. The Ab Roller is simple, easy to use and the compact size allows you to easily store when not in use or pack for use on the go while traveling.
