ABSTRACT:
An exercising device is disclosed herein for promoting blood circulation and muscle toning which includes a plurality of elongated rod sections which are removably connected together in an end-to-end relationship to provide an elongated, composite shaft or bar of fixed length intended to be retained across the shoulders of the user by grasping the opposite ends of the composite shaft or bar or alternately for flexing the shaft or bar by the hands of the user. The adjacent ends of the rod sections are detachably joined together by a threaded coupling having a projecting threaded member insertably received within a threaded cavity of a receptacle member. External flanges and internal shoulders are cooperatively carried on the respective members for limiting coupling insertion and for properly seating the members together whereby a smooth and regular external surface is provided on the shaft or bar and which permits flexure of the shaft or bar without breakage or damage to the shaft on the coupling members during use.
