<p>A gyroscopic exercise device has a pair of handles attached to a housing. A user holds and rotates the handles along cone-like paths causing precession of a rotor, which is rotating about its spin axis, to provide resistance to the user. The device has an axle disc that holds ends of an axle of the rotor. The periphery of the axle disc and the ends of the rotor axle are within a circular race in the housing. A retracting spool allows pull starting. An optional motor attached to the axle disc has a wheel for rotating the rotor about a spin axis by a temporary supply of power from included batteries in one of the handles. An optional abdominal rolling ring provides abdominal exercise.</p> |
