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.
