Abstract: A balance board-training device made up of a training board, a pivoting device permanently connected to the underside of the training board and a rolling device that is configured and positioned so as to be able to roll across the underside of said training board. In use a rider stands on the upper side of the board or deck. As the rider moves, the one portion of the device pivots upon the dome shaped pivoting mechanism and the other end of the device moves and is able to move both side to side, as well as in a rising and falling motion as the rolling device of the present invention moves beneath the board.
