Balance boards have been widely used by young and old alike to increase balance and strengthen the core. This wood balance board measures 15.7" in diameter and has a textured surface for added safety. The most common use is standing on the board and shifting weight side to side while not letting the edge of the board touch the ground. The board can be used for more advanced moves like squats, push ups or standing on one foot in the middle of the board, with the other foot in the air. The board is portable so take it to the office, or on vacation. By Trademark Innovations. Ages 14+.
