Abstract: A system for supporting a user's arm, comprises an armrest. The armrest is suspended and supported from a horizontally movable structure comprising a vertically movable member through which the armrest is suspended, a counterbalancing return-force producing assembly connected to the vertically movable member to counterbalance at least in part the weight of the user's arm, and a movement-resisting assembly connected to the vertically movable member to resist to vertical movement of the vertically movable member. According to a preferred embodiment, the vertically movable member comprises a cable, the counterbalancing return-force producing assembly comprises a first, spring-loaded reel, and the movement-resisting assembly comprises a second reel on which turns of the cable are wound and provided with at least one lateral face, and at least one friction disk applied to the lateral face of the second reel to resist to vertical movement of the wire.

Abstract: Boxing exercise apparatus has an adjustable frame that can selectively adjustably support different types of punching bags in optimum position to be struck with the hands and/or feet of a person or persons using the apparatus. In particular, the frame is releasably attachable to a conventional treadmill for simultaneous use of the boxing exercise apparatus and the treadmill. In one form of the invention, the frame is capable of being free-standing independently of use with a treadmill, and in another form the frame relies upon its attachment to a treadmill to support it in an operative upright position.
