1. An exercise bar assembly, comprising:
a pair of rotating grip assemblies, each including a generally planar frame and a hand grip mounted within the frame for rotation within the plane of the frame, each hand grip including a post extending perpendicular to the plane of the frame;
a center bar assembly defining a longitudinal axis and opposite ends along the longitudinal axis, each of the opposite ends fixed to said frame of a corresponding one of the rotating grip assemblies along the longitudinal axis; and
an elongated elastic element having opposite ends, each of said opposite ends configured to be removably mounted on a post of a corresponding one of said pair of rotating grip assemblies with said elastic element extending along said longitudinal axis, said elastic element resisting rotation of said hand grip in each of the rotating grip assemblies,
wherein each of said rotating grip assemblies includes a fixed bearing post, separate from said post, projecting perpendicularly from said frame and arranged on said frame to contact said elastic element upon rotation of said hand grip.
