A system combining ski training and exercise includes side-by-side swing arms which are pivotally mounted on a frame with lower ends being free to swing through first and second arcs, respectively, resulting in both lateral and elevational travel of the lower ends. For receiving the associated foot of a subject, each swing arm has a foot platform mounted for elevational travel therealong as imparted by the subject between the upper and lower ends. The foot platforms are interconnected enabling the subject whose feet are received thereon to selectively cause the left foot platform and the right foot platform to travel elevationally and the left swing arm and the right swing arm to travel through first and second arcs, respectively, to thereby perform a series of successive stances and movements both laterally and elevationally which simulate a skiing run. The system of the invention may use ski boots and bindings, or other arrangements, for receiving the feet of the subject on the foot platforms. In one embodiment, the left and right foot platforms may be so interconnected as to cause stepping travel thereof; in another embodiment, they may be so interconnected as to cause hopping travel. To simulate actual conditions, drag is imparted to the elevational travel of the foot platforms and the arcuate travel of the swing arms can be braked according to the positioning of the subject's feet. Ski poles are attached to the frame by an elastomeric member providing universal hinged movement.
