Exercising device including linkage for control of muscular exertion required through exercising stroke

摘要

An exercising device having an exercising member, an assembly mounting the member for movement along a curved path of travel, a pneumatic system operable to provide a force resisting movement of the member, a linkage interconnecting the pneumatic system and the member and having a pair of pivot points adjacent to said member, and a stop borne by the member and engageable with the linkage during movement of the member discriminately to control the pivot point about which relative movement between the linkage and member is accommodated to control the force required to operate said pneumatic system.
