Wobble Boards Wobble boards have a circular deck perched upon a permanently mounted bulb on the bottom of the board. This allows the board to rock in all 360º. This allows training by tilting the board in all 360º with the goal of keeping the deck’s edge off of the ground. The maximum tilt is when any point along the edge of the deck touches the ground. The maximum tilt is typically shallow angle. For both the Large Wood Wobble Board and the Small Hard-Plastic Wobble Board, the maximum tilt is about 16º.
