  • Patent number: 5873805
    Abstract: A wrist exercise device has a tube-like handle with rubber grips proximate each end. Resistive tubing is attached to the center of the handle at one end of the tubing, and is attached to a strap at the other end of the tubing. The attachment to the handle is made by an aperture in the handle through which an end of the tubing is passed, and a ball is friction fit into that end of the tubing. The tubing is similarly connected to the strap by forming an aperture in the strap, reinforced by a grommet, and friction fitting a ball into the end of the tubing which is passing through the strap. An exerciser uses the device by anchoring it by passing, for example, a foot through the strap or holding the strap and by pulling or rotating or otherwise moving the handle against the resistance of the resistive tubing. Resistance may be increased by winding the tubing around the handle a desired amount.
