Abstract
A portable exercising device is disclosed having a toroidally shaped inner chamber. A free moving body is disposed within the chamber. In use, the free moving body is placed into rotation within the chamber. The angular momentum of the body provides a resistance to motion to enhance the exercising effects. In the preferred embodiment, the device is ring-shaped and includes an elongated handle mounted through a center aperture. The device may also be used as a muscle tension reliever and as a coordination developer.
Claims5
An exercise apparatus comprising:
- a toroidal member having a circular cross-section of a diameter to facilitate gripping, said member further having a sealed uniform inner chamber of circular cross-section;
- an elongated handle extending linearly across the toroidal member and connected thereto to provide an alternate gripping means;
- and
- a spherical body located within said sealed inner chamber, with the diameter of said spherical body being slightly less than the diameter of the chamber to produce continuous sound upon rotation thereby permitting the user to gauge the speed of rotation of said body, and with said body having a fixed weight and a density greater than the material forming the toroidal member such that at rest, the apparatus is easy to carry, but upon rotation, the angular momentum of the body is sufficient to create resistance to movement in the plane of rotation of the body thereby providing exercise.
