Abstract
A rhythmic exercising apparatus formed of an annular body with a hole large enough to receive a foot therethrough and being provided with an index orientation member integral therewith for directing the position of the apparatus with respect to the travel of the user. The lower surface of the body is provided with grooves or ridges to prevent it from sliding. The annular body is also formed to minimize braking by tensile forces acting thereon through provision of a cut or slit therein.
