Abstract
The exercise device includes a support frame upon which a first shaft is rotatably supported. A user interface member is connected to the first shaft such that when the user interface member is displaced by a user, the first shaft is caused to rotate. A second shaft is also rotatably supported on the support frame. A torque arm assembly having a plurality of torque arms is connected to the second shaft. Each of the plurality of torque arms is adapted to support a weight member thereon. A conversion mechanism connects the first and second shafts to control the relative rates of rotation of the first and second shafts such that the resistance force generated by the torque arm assembly remains positive over an entire range of motion of the user interface member.
