Abstract
A rotatable disc exercise apparatus includes a first disc having a first outer planar surface and a first inner surface, a second disc fastened to the first disc and rotatably supported on the first disc by a first annular set of ball bearings and a second annular set of ball bearings. The second disc has a second outer planar surface and a second inner surface facing the first inner surface. A single biasing member sandwiched between the first and second discs resiliently biases the second disc to a neutral rotational position between the discs. The first annular set of bearings is captured between the inner surfaces by an annular outer wall of one of the discs and an inner annular rib of the other one of the discs. The second set of bearings is carried in an annular race between the first and second inner surfaces.
