ABSTRACT:
A drive unit for providing kinetic frictional resistance to an exercising apparatus which includes a sub-frame with a driving and driven element coupled to the sub-frame a motor coupled to the driving element for rotatably driving the latter. The driving and driven elements are coupled such that the driving and driven elements slip relative to one another. An adjustment is provided for adjusting the kinetic friction force between the driving and driven elements, while a stop is mounted on the sub-frame for blocking the driven element from movement beyond a start position. In operation the driving element is continuously driven by the motor throughout an exercise so that only kinetic friction has to be overcome by a user.
