Dyna Board 20"
The DynaBoards are designed to assist in the use of the Dyna Discs. The boards come in 15", 20" and 30" circles. Simply place the hole in the board over the DynaDisc so the logo of the disc is shown. This assures correct alignment. The small board can be used with one foot, the 20" with two, the 30" with a wider two foot stance and/or sitting cross leg, and the rectangle board can be used as a surf or skate board as while on all fours for back stabilization. Change the air in the DynaDisc to change the height of the board, range of motion for the use and level of difficulty.
*DynaDisc sold separately.
