An exercise device for simulating cross-country skiing in which the user stands on a pair of footplates movably mounted on longitudinally extending rails of a base frame. U-shaped channels formed in the rails receive rollers mounted on the footplates to maintain engagement of said footplates with the rails. A belt is connected to the footplates and slideably extends about a plurality of rods mounted on the front and rear ends of the base frame, to reciprocate the footplates in unison in opposite directions along the rails. A tensioning bolt is mounted on one of the footplates and is connected to the belt for adjusting the resistance to the movement of said belt and footplates. A pair of levers which simulate ski poles are pivotally mounted on the front end of the frame. An adjustable resistance mechanism comprising a pair of plate members extends transversely across the front end of the frame and clampingly engages an extended end of each of the levers. A plurality of friction pads are positioned intermediate the plate members and the levers to provide frictional resistance to the pivotal movement of said levers. A centrally located adjustment bolt equally adjusts the gross resistance applied to the levers and arm movements of the user when reciprocating the levers, and a pair of outer adjustment bolts each selectively adjust the resistance applied to a respective one of the levers.

An exercise device including: (a) a base frame having front and rear ends and at least three spaced, parallel elongated rails extending longitudinally between said ends; (b) a pair of footplates, each movably mounted on a certain pair of the rails for reciprocating movement along said rail pairs; (c) belt means extending along the rails and connected to each of the footplates for moving the footplates in unison in opposite directions along the rails; (d) a pair of levers pivotally mounted on the base frame adjacent the front end thereof, each of the levers having an extended end extending toward each other generally along the front end of said base frame; (e) plate means located adjacent the front end of the base frame and operatively engageable with the extended ends of the levers for providing frictional resistance to the pivotal movement of the levers; and (f) adjustment means for selectively clamping the plate means against the extended ends of the levers for equally adjusting the gross resistance to the pivotal movement of both of the levers and for independently adjusting the resistance to the movement of a respective one of the levers.
