An exercise fixture comprising upper and lower horizontally arranged, spaced apart, platforms, with the two platforms connected together by a centrally located vertically arranged spindle. The upper platform forms a seat upon which a user may sit during exercising. The spindle has a tapered surface portion adjacent the upper surface of the lower platform, and an upper portion which engages the upper platform. The tapered surface portion is generally in the shape of an inverted, truncated cone which engages the lower platform when the spindle is tilted relative to the horizontal lower platform. The upper platform may be tilted relative to the lower platform so that the spindle surface portion contacts the lower platform to limit the degree of tilting. Thus, a user seated upon the upper platform may repeatedly rock forwardly and rearwardly or from side-to-side until the conically shaped surface engages the lower platform so that the user may exercise portions of the user's body.
