Abstract: A precessional gyroscopic exercise device includes a housing containing a tiltable rotor assembly. The housing and the rotor assembly may be coupled together by a tilt assembly that defines a fixed precession axis for the rotor assembly and allows the rotor assembly to be tilted relative to the fixed precession axis. When the rotor is spinning, and the rotor assembly is tilted contact between the spinning axle and the interior surfaces of a circumferential channel in the housing causes the rotor assembly to rotate about the fixed precession axis, producing a gyroscopic precessional torque—this torque, and resultant wobbling of the device, is opposed by the user for the exercise effect. The tilting mechanism may be associated with handles on the outside of the device, allowing the user to selectively control the tilting of the rotor assembly. The handles may be rotatably coupled to the device, permitting operation of the device using a pedaling motion.

The device includes a frame, which supports a track, preferably a pair of linear bearing rods one on each side. A guide member, or linear bearing runs on each bearing rod and is attached to a handle or bar that is grasped by a user.

A primary tether guide is preferably coupled to the frame and can be positioned near an intermediate rotational position of the swing arm where acceleration forces are transferred into deceleration forces.
