A compact exercise device ( 10 ) of the type wherein a person grips handle devices ( 12, 30 ) lying at opposite ends of a rope that extends through a housing ( 22 ), the person pulling one end of the rope away from the housing while resisting movement of the other end of the rope towards the housing to exercise. A windup spool ( 114 ) lies in one of the handle devices and a spring ( 130 ) urges the spool to wind up rope by a spring, but the spool is normally prevented from turning in either direction by a release mechanism ( 110 ). A person who holds a handle grip ( 100 ) with most fingers of his/her hand, uses his/her thumb to depress a button ( 90 ) to operate the release mechanism. While the thumb continues to depress the button, the person moves a handle device away from the housing to lengthen the effective length of rope, or moves a handle device towards the housing to shorten the effective length of rope. In another device, windup spools ( 226, 228 ) lie in the housing, and a person depresses a button ( 202 ) on the housing to operate the release mechanism.
