Abstract
A weight lifting exercise apparatus capable of multiple maximum and minimum segments of resistance force is provided. The apparatus disclosed includes a free-standing support frame within which a weight support carriage having detachable weight members is supported for vertical movement. A shaft is rotatably mounted on the frame and an exercise bearing member which may be engaged by a user is secured to the shaft as well as a cable wheel having a circular arc segment. A length of cable is secured at one end to the weight support carriage, reeved through cable guides and attached at its other end to the cable wheel. A fixed support disk is secured to the shaft and a first rotatable disk which supports a first torque arm is rotatably mounted on the shaft. The first torque arm supports a moveable weight and the first disk may be variably attached to the fixed disk. A second torque arm is also rotatably supported by the shaft, supports a second weight member and may be secured to the first disk. Because the initial positions of the first and second torque arms and weight members may be variably preselected, a myriad of resistance force patterns are available.
