The Extreme Balance Board is another amazing device to improve your balancing skills. The Board moves pretty much in all directions, side-to-side, forward, and back, and at all angles. The Extreme Balance Board differs from other balancing boards in that it features a tiny curved wooden rocker, which is connected to the main board by a flexible center piece. The center piece, in combination with the curved rocker, can turn in all directions and at a variety of angles. What I like about this set-up is that it is more versatile than boards with a static build since you are able to adjust the amount of swiveling and thus make balancing either easier or harder. All you need to do is remove a set of plugs located at the center piece. The plugs are intended to restrict some of the motion and by removing them the board becomes considerably more wobbly and harder to balance. I really enjoyed trying out the Extreme Balance Board and can highly recommend it as an outstanding tool that not only helps in building muscle but also improves balance, core strength, reaction time, and coordination. All the important stuff you need to be able to shine on the slopes.
