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.

An exercise device for generating a plurality of resistance curves comprising: a support frame; a shaft rotatably supported on the support frame; a user interface member connected to the shaft which when activated by a user causes the shaft to rotate; a resistance generator connected to the frame which can generate a plurality of resistance forces; a transfer assembly for transferring a pre-selected force from the resistance generator to the shaft and thus to the user interface member; a torque assembly for applying a torque which can vary in magnitude and direction to the shaft comprising a plurality of weight members supported on at least three torque arms secured to the shaft at a predetermined angular position of 120°from each other such that the resistance curve experienced by the user during an exercise motion can be changed by the positioning of the weight members on the torque arms.
