Abstract
A variable resistance exercise device is provided which enables a user to select from an almost limitless set of resistance curves having various shapes and amplitudes. These results are achieved using a baseline fixed resistance and a variable resistance generated by a torque arm assembly. Preferably, the torque arm assembly has a vertical diametric torque arm and two horizontal radial torque arms which are perpendicular to the vertical torque arm. By varying the position of a weight member on each of these arms, as well as the ratio of the net horizontal torque and the vertical torque generated by the weight members, the resistance curve that the user experiences can be infinitely varied. Additionally, through the use of a gear assembly, the user can achieve a force variance during the exercise which is greater than the minimum force experienced during the exercise.
