发明名称 Exercise apparatus with rotational grips
摘要 A barbell with rotational grips. The barbell includes a center bar with two grip housings of annular configuration mounted to opposite ends of the barbell. Handgrips are located within the grip housings. Two sets of bearings are diametrically opposed to one another at the ends of each handgrip. A first set of radial wall bearings are perpendicular to the rotational axis of the handgrip, and a second set of sidewall bearings are parallel to the rotational axis of the handgrip. Each grip housing has an interior circumferential groove, with radial and sidewall bearings operatively secured within the groove. Each hand grip is spring-loaded so that a constant force is applied perpendicular to the rotational axis of the handgrips.
