ABSTRACT:
A weightlifting bar, which is adapted for use as a barbell, comprises a straight center section having a longitudinal axis, a pair of connector sections extending radially outwardly from each end of the center section, and a weight-receiving side section extending sidewardly from the extended end of each connector section and radially inwardly at an acute angle toward the longitudinal axis. Each of the connector sections is freely rotatable about the center section, and each of the side sections is freely rotatable about its mounting in its connector section. The bar, with weight plates symmetrically loaded on the side sections, and supported by its center section, has a center of gravity that is substantially lower than the center section, and substantially constant with respect to the center section regardless of the rotational position of the center section about the longitudinal axis.
