ABSTRACT:
An exercising apparatus for simulating skating and skiing motion in which outward and opposite unilateral movement of the user's feet ultimately drives a momentum storage member which can be a flywheel. The apparatus has a base for supporting a track having left and right distal ends. The track positions and restrains foot carriages to approximately horizontal movement. The foot carriages support the user's feet so that when the user's left foot extends outwardly and to the left of user's body the left carriage moves towards the left distal end of the track, and when the user's right foot extends outwardly and to the right of user's body the right carriage moves towards the right distal end of the track. A driven pulley is supported by the base and drives the momentum storage member. The apparatus has a first subassembly having unilaterally acting first engaging member and first transmission, and a second subassembly having unilaterally acting second engaging member and second transmission. The first subassembly drives the driven pulley in a drive direction when the left carriage moves towards the left distal end and does not drive the driven pulley when the left carriage moves towards the right distal end. The second subassembly drives the driven pulley in the drive direction when the right carriage moves towards the right distal end and does not drive the driven pulley when the right carriage moves towards the left distal end. The momentum storage member provides resistance to outward movement of the carriages. A variable braking force can be applied to the momentum storage member.
