ABSTRACT:
An exercise device which can be fixed to a support and through which a rope is pulled against the force of frictional engagement within the exercise device. The resistive force against the pull is determined by the number of turns of the rope about a center shaft in the exercise device. The force is indicated by an improved indicator which moves longitudinally in the device as the number of turns is changed and which can be viewed for determining the frictional force.
