ABSTRACT:
An exercise device has a cord contained in a housing with a handle on the cord to pull it out of the housing. Resistance is developed by sliding friction between the cord and the housing and between the cord and a spool in the housing. The device has independent adjustment for controlling the friction between the cord and the housing and the spool friction. A recoil wheel retracts the cord.
