ABSTRACT:
A load applying driving apparatus for an exercise device of any kind includes a motor providing a counterforce, a crank mechanism operatively connected to the motor and a flexible transmission member for transmitting the counterforce from the motor via the crank mechanism to a user-actuated member of the exercise device. Upon exercise, the motor exerts a load on the user-acutated member when the user carries out the lifting stroke and the return stroke.
