Abstract
An exercising device adapted to be fixed to a support and including an elongated shaft around which a rope is wrapped as it passes into and out of the device. The exercise device includes a hub having off-center openings through which the rope is passed. The hub normally is locked against rotation but can be unlocked for rotation relative to the shaft in a combination ball and race structure which both indicates the relative position of the hub and the shaft and releasably locks the hub against rotation about the shaft. Turning the hub changes the rope turns about the shaft to adjust the pull on the device.
