ABSTRACT:
A variable resistance physical exercise apparatus is provided which provides improved features over prior art devices in that it is more compact, provides a linear resistance profile to the user and provides a variety of modes of operation. The device comprises a motor driven bi-directional linear translation mechanism to vary the effective length of a lever arm and therefore vary the weight of resistance to the user. An alternative embodiment includes a spring winder drum pulley combination.
