Exercise and massage device
View Patent ↗An exercise and massage device utilizes a substantially spherical body having a central cavity that extends to opposite sides of the spherical body so that the cavity forms openings on opposite sides of the spherical body. The spherical body has an outer core of a first resilient hardness. A single rigid handle is positioned within the cavity. The openings of the cavity are sized and configured for allowing a user to access and manually grasp the handle through either opening. A resilient outer layer surrounds the outer core of the spherical body and provides an exterior surface of the spherical body. The resilient outer layer has a second resilient hardness that is less than that of the first resilient hardness of the outer core of the spherical body to provide a cushioning effect when the device is used in a massage mode. The device is weighted to provide a total weight of the device of from 2 lbs or more.
