Abstract: A resistance assembly (13) is disclosed for use in an exercise apparatus having a movable element (18) connected to a progressively increasing resistance assembly (13) by a cable (34). An exercise machine (10) employing the resistance assembly (13) is of a multipurpose type comprised of a frame (12) having an upright member (26) with a backrest (32) and a seat (30) attached thereto. The movable element (18) is operably associated with the frame (12) for movement by a user in performance of exercises resisted by an attached elastic resistance member (16). The elastically responsive resistance member (16) is selectively secured at one end to the upright member (26) to be positionable at one of a plurality of positions. A biasing device (20) to bias the force exerted by the resistance member (16) on the movable element (18) is accessible to a user in a seated position.
