Weight Bar Exercise Apparatus

Abstract

A weight bar assembly comprises a first bar, an extension bar, and a weight. The first bar comprises an elongated cylindrical shaft and a collar. A diameter of the collar of the first bar is larger than a diameter of the elongated cylindrical shaft of the first bar. The collar of the first bar divides the elongated cylindrical shaft into a first exposed portion and a second exposed portion opposite the first exposed portion.
