US Patent 8382647 Weighted exercise device providing two grips

Weighted exercise device includes a generally hemispherical body defining a hollow cavity opening at a first edge of the body, and an outwardly projecting rim arranged on the body proximate to the first edge. A handle is arranged in the cavity. The rim provides a first grip during use of the device and the handle provides a second grip during use of the device. By providing two different grips on the same weighted device, and due to the symmetrical rounded shape, with a low center of gravity, the weight is evenly distributed around a user's hands, and a user can safely and efficiently perform a larger variety of exercises in comparison to using conventionally shaped exercise devices that include only a single type of grip.
