Get more out of every motion with the VIM Ab Roller's unique, patented 3-wheel triangular design that offers you the confidence of enhanced stability. This is perfect for beginners, keeping the roller grounded both while rolling out and back inwards. To improve workout safety and enable a wide variety of workouts at full range, a standalone stopper wedge is included. Position it at your tolerance edge to be stopped exactly where you want and still have the strength to return the motion. Rubberized soft-grip handles help minimize hand fatigue while exercising, and the slip-free material provides ample grip even in the sweatiest of home exercise environments. It may be a small, simple looking, compact, lightweight and portable device, but our ab wheel roller rapidly strengthens and tones your entire body from head to toe by hitting your abs, core, torso, shoulders, arms, upper back and lower back.The ab wheel ships fully assembled for out-of-the-box use.
