发明名称 Exercise machine for hockey players
摘要 An exercise machine for hockey players includes a cable elastically tethered to a frame on one end and to the blade of a hockey stick on the other. A first pair of pulleys are mounted to the base of the frame while a second pair are suspended above from springs. The cable runs over a first elevated pulley, under a base mounted pulley, over the other elevated pulley and back under the base mounted pulley wherein the springs provide a retracting force on the cable as it is pulled away from the machine by the blade of the hockey stick.
