ABSTRACT:
The exercising device has a housing which is attached to a stationary surface. A cord which has a hand grip on its free end can be pulled out of the housing against the adjustable internal resistance of the exercising device. A spring-powered cord retractor reel rewinds the cord back into the housing when the cord is released. The cord runs from the retractor reel around a plurality of sequentially arranged capstans and then out of the housing. The internal resistance on the cord is preset with manually operated push buttons which lock a selected number of capstans so that they will not rotate in the unwind direction. The remaining capstans are permitted to freewheel in the unwind direction. The push buttons can be set to produce a wide variety of cord resistance force levels.
