US Patent 10159868 Bar-bell design with rotatable hand grips

A weight lifting apparatus is provided and includes a pair of weight supports, a pair of handle assemblies coupled to the pair of weight supports, and a central bar interposed between each handle assembly of the pair of handle assemblies. The central bar is coupled to each handle assembly. Each handle assembly includes a handle housing, a grip that is rotatably supported within the handle housing, and a ratchet pawl. The ratchet pawl is selectively manipulatable from a first position that inhibits rotation of the grip relative to the handle housing to a second position that permits rotation of the grip relative to the handle housing.
