ABSTRACT:
A multiple purpose wall mounted adjustable exercise device has an upstanding elongated frame including two upright spaced parallel guide posts and an upper pulley and a lower pulley attached to the upper and lower portions of the frame, respectively. A resistance means operatively connected to the frame provides an exercising force in response to exercising motions of the user. A two-ended cable is trained around the upper and lower pulleys with its ends connected to the resistance means. A grip slidably attached to an intermediate portion of the cable is trained around and between two guide pulleys attached to a carriage that is carried by the frame. Guide pulleys guide the intermediate portion of the cable laterally outwardly from the carriage to provide a working loop for engagement by the grip. The height of the carriage is selectively adjustable relative to the frame. The length of the working loop remains substantially constant when not pulled, regardless of the height of the carriage. The resistance means may comprise resiliant elastic straps, coiled springs or weights.
