ABSTRACT:
A press exercise machine allows the press arm of the machine to be adjusted to various rest positions without creating slack in the system. The machine has a frame that supports a seat and a weight stack that is mechanically coupled to a press arm by a cable. The press arm is adapted to be rotated on the frame, wherein the cable is pulled and the weight stack is lifted from a rest position. In the rest position, the press arm abuts against a sleeve which can slide along an adjustment arm that extends from the frame. The user can move the sleeve to a number of locations on the adjustment arm to vary the rest position of the press arm. The cable is coupled to a first pulley that is attached to the sleeve and a second pulley that is attached to the arm. The cable is also guided by a third pulley that is attached to the frame. The spatial relationship of the pulleys is such that the cable remains slack free for all rest positions of the press arm.
