Abstract
An exercise device for simulating cross-country skiing includes a plurality of longitudinally extending channel members mounted on cross frame members so as to define elongated slots in which trolleys for foot supporting members and hand engaging members can reciprocate. A control system interconnecting the foot supporting members and hand engaging members includes a main drive pulley interconnecting the foot supporting members for coordinated reciprocal movement and a secondary belt interconnecting the foot supporting members and hand engaging members so that each hand engaging member will reciprocate in an opposite direction to its associated foot supporting member and at a speed of twice that of the foot supporting member. A resistance structure is provided for resisting movement of the trolleys to provide a selected level of exercise.
