For abs training you ideally need to work the muscles from different angles, vary the speed of the movement and train the muscles at each end of the muscle group. Ab wheels allow for training of both ends of the abdominals, and its easy to vary the tempo and resistance by using either the feet or knees for support. Add a weight vest for even greater resistance!
Our ab wheels use a steel central shaft, making them suitable for users up to 100kg in weight.
