Abstract
An exercise device for simulating cross-country skiing in which the user stands on a pair of foot plates moveably mounted on a pair of tracks extending along a base frame. A pair of endless flexible belts extends about rollers located at the front and rear of the frame and extend along the tracks beneath the foot plates. An eccentric cam is mounted on the bottom of each of the foot plates and drivingly connects the foot plate to its respective belt by clamping the belt against a bracket upon movement of the foot plate in a rearward direction and which releases the clamping engagement with the belt upon movement of the foot plate in the forward direction to simulate movement of a pair of cross-country skis. An adjustable brake provides resistances to the movement of the belts when the foot plates are moved in the rearward direction. A pair of hand manipulated tension cables are mounted on a pedestal to provide resistance to arm movement of the users to simulate operation of ski poles.
