A skier's exercise trainer has a base providing a front support and right and left rear lateral supports, with a transverse rear track portion extending laterally between the lateral supports. A pair of elongated ski plates are positioned side by side overlying the base with their front ends rockably and pivotally mounted near the front support of the base, and their rear ends spaced above the rear track. A truck assembly is rockably joined to the underside of the rear end of each ski plate, with an elongated tie bar pivotally connected to the underside of each truck, and a rolling support is rotatably secured to each truck in rolling contact with the rear track. A tension-carrying cable has a rear end connected to the central portion of the tie bar and extends forward under the ski plates between a pair of guide rollers rotatably mounted on the base in front of the tie bar. An adjustable tension spring assembly connects the front end of the base to the forward end of the tension-carrying cable. The device enables a user standing on the ski plates, by shifting his weight to apply pressure to the "uphill" ski, and changing "edge set" to establish reverse turn. The device thus simulates the motions of a downhill skier making a slalom-style run, with the spring assembly simulating the edging force produced by snow.
