An apparatus designed to allow the user to simulate the action of a snowboard during dryland training. The apparatus has a cylindrical roller that has tapered or angled surface at the outer portions of the roller. The tapered sections may have slots cut into them which would allow for a stepping effect from one tapered surface to the other. Attached to the lower surface of the receiving board are spacers. These spacers provide stability to the apparatus, while at the same time permitting unconventional radial, lateral and yaw motions to the receiving board and roller. The receiving board is attached to the lower surface of the upper deck by using vertical lifts attached between the receiving board and the upper deck. The receiving board may also include a gripping surface material between the lower surface of the receiving board and the roller. The upper surface or deck of the apparatus has a concave outer edge to provide increased surface contact with the feet of the user. The center of the roller has a large slot cut therein to receive a guide rail connected to the horizontal centerline of the lower surface of the receiving board in order to keep the board center over the roller. The guide rail has adjustable end stops that allow the individual to change the length of the rail. The apparatus may provide an axle located through the centerline of the roller that would permit the attachment of a bearing and wheel at the end of the tapered sections to allow for a tighter turning radius for the apparatus.
