Reference.com states that a barbell is a piece of equipment that is used in various exercises. A barbell is made up of a steel bar connecting two pieces of steel on both sides of the bar. The bar is also where users will place their hands when using the equipment. Larger barbells can have weights slid onto either side of the bar to achieve the desired amount of weight. The optional weights are usually kept in place by collars to make sure that they do not slide off the bar. In Olympic sports, women's bars typically weigh less than men's bars. Women's bars also have less hand space.
