Abstract: An angularly adjustable ski deck is selectively downwardly or upwardly inclinable. A stand is pivotally connected to a frame, which frame rotatably supports a pair of belt rollers at either end thereof along a line transverse to the length of said frame. An endless belt is mounted around the two rollers, and is adapted to be moved in a single direction against the movement of a skier. A pair of slide tracks are formed within the belt to simulate a cross-country skiing path. Ski-on and ski-off ramps are provided at either end of the ski deck.
