<p>An exercise device comprises a rigid endless tubular ring having an internal bore, a handle element extending radially across a main aperture bounded by the ring, and a weighted freely movable element received in said ring for movement therearound. The handle element is attached to the tubular ring via first and second attachment portions which extend around the tubular ring for improved stability. By gyrating the exercise device to cause the ball to roll within the ring, a user is able to generate inertial resistance within the device and improve the strength in his or her wrist and other body parts. The exercise device is designed to be used in a one-handed or two-handed mode of operation. The attachment portions extending around the tubular ring stabilize the junction between the ring and handle, allowing greater ball weights and larger diameter rings to be used.</p> |
