Abstract: An exercise apparatus including a frame having a front portion and side portions, independently movable foot platforms connected to the frame, the foot platforms being movable in at least fore-aft and lateral directions, each of the foot platforms comprising a carriage and a movable portion, the movable portion being configured for elevational movement with respect to the carriage so as to provide a variety of exercises involving independent leg motion in any one, two or three axes and independently variable generally opposing resistance modules connected between the foot platforms and the frame where the variable resistance modules are configured to independently control elevational travel of the movable portion and fore-aft, abduction and adduction movement of the foot platforms and are conveniently adjustable during or before use.

Abstract: 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.
