An exercising apparatus using an elastic or spring type resistance provides a relatively constant controlled resistive force throughout an entire exercising stroke. In the exemplary embodiments, a multiple pass pulley arrangement attached to elastic rubber straps provides tension on a cable that is threaded through the multiple pulleys and extends at either end through openings in an elongated housing. An external hand grip is secured to one end of the cable to be grasped or otherwise engaged by the user and the other end can be adjustably secured in one of a series of detent stops along the length of the housing to set various resistive levels. The housing is secured at each end with an eccentrically placed swivel that facilitates free lateral movement in performing the exercise stroke.
