ABSTRACT:
An exercise device includes a base plate, a turning disc mounted above the base plate for rotary and orbital movement with respect thereto, and bearings interposed between the base plate and turning disc. A cover is attached to the turning disc and is adapted to support the weight of a user who imparts rotary and orbital movement to the cover and thereby to the turning disc. The turning disc has therethrough a central opening. A device is supported by the base plate and cooperates with the edge of the opening in the turning disc to limit the range of orbital movement of the turning disc with respect to the base plate. An adjusting device is associated with the limiting device for selectively adjusting the range of the orbital movement of the turning disc.
