ABSTRACT:
An exerciser that includes a stretchable tension member connected to an adjuster mechanism which permits the tension member's length to be varied as desired by the user. The adjuster mechanism, in preferred form, includes a housing that defines a cavity open through a port to atmosphere. A free end of the tension member is looped around a latch pin within the cavity, both ends of the loop extending through the housing's port. The latch pin, which is accessible to a user from exteriorly of the housing, is movable within the cavity away from the port when it is desired to adjust the tension member's length, and is movable within the cavity toward the port when it is desired to lock the tension member at the desired length. The cavity includes wedge shaped interior walls that flare away from the port, and that cooperate with the pin and the tension member's looped end, to establish the locking position of that looped end.
