Physical exercise apparatus










Image Number 3 for United States Patent #4799667.

The invention relates to a physical exercise apparatus comprising three nested frame elements mounted inside one another for rotation about axes offset by 90.degree. from one another. The thus established gimbal mounting of the frame elements permits a person occupying the innermost frame element to assume any angular position in space solely by displacing his weight to thereby fortify his muscles an improve his sense of equilibrium.
