A balancing apparatus includes a platform that tilts upon a hemisphere attached to the lower surface thereof. The platform has a grooved track along its periphery. The outermost wall of the track is inclined. A ball is movable around said track upon tilting of the platform and can climb the outermost wall of the track when moved at a fast speed. The ball adds resistance to the tilting of the platform.
