ABSTRACT:
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.
