A barbell is a specialized piece of exercise equipment used for weight training. It is central to many disciplines, including bodybuilding, powerlifting, and Olympic weightlifting.

The tool consists of a long metal bar with weights attached to each end. To adjust the resistance, users slide weight plates onto the outer portions of the bar. To ensure safety, collars are used to secure these plates. This prevents them from moving unevenly, which would cause dangerous, unbalanced forces during a lift.

The mechanical design of a barbell varies depending on its intended use. The central portion of the bar is called the shaft. This shaft often features a knurled crosshatch pattern. Knurling is a textured surface that helps lifters maintain a solid, secure grip. The outer portions of the bar are known as sleeves. In competitive bars, these sleeves are designed to rotate. This rotation allows the weights to move smoothly without twisting the lifter's wrists.

Olympic weightlifting requires very specific barbell characteristics. A men's Olympic bar is 2.2 meters long and weighs 20 kg. It has a 28 mm diameter grip section and 50 mm diameter sleeves. These bars must possess "whip," which is the ability to store and release elastic energy. Women's Olympic bars are also used in high-level competition. They are shorter and lighter, weighing 15 kg with a 25 mm grip diameter. Unlike men's bars, women's bars do not have a center knurl.

Powerlifting is another major discipline that utilizes different bar specifications. Powerlifters often require much stiffer bars to manage extremely heavy loads. For example, a deadlift barbell is typically the longest and most flexible type of bar. This flexibility can actually help more weight be lifted. Powerlifting bars use simpler, robust bushings instead of high-speed bearings. The International Powerlifting Federation (IPF) mandates that bars must be between 29 mm and 32 mm in diameter. These bars are also used by both men and women in competition.

Weight plates also differ based on the sport being practiced. Olympic lifters frequently use "bumper" plates, which are coated in solid rubber. This coating allows them to be safely dropped from overhead heights. The International Weightlifting Federation (IWF) uses a strict color code for these plates. For instance, a 25 kg plate is yellow, while a 15 kg plate is white.

In contrast, powerlifting plates are often made of cast iron and are much thinner. Being thinner allows lifters to fit more weight onto the bar for heavy attempts.

The history of the barbell includes a major technological turning point in 1910. A company named Berg produced a revolving barbell designed by Veltum. This invention allowed the bar to revolve easily during a lift. Following the 1928 Amsterdam Olympic Games, these revolving barbells became highly popular. By the 1960s and 1970s, many gyms worldwide began using these modern designs.

Before this, equipment was often less specialized for the mechanics of the lift.

Many other variations of the barbell exist for specific training needs. The EZ curl bar, originally called the Dymeck curling bar, features a curved profile. This shape allows the wrists to stay in a more neutral position during exercises like bicep curls. This design can help reduce the risk of repetitive stress injuries.

Some lifters also use a barbell pad, or squat pad, for added comfort. These pads provide cushioning when the bar rests on the spine during high bar squats or on the pelvis during hip thrusts. Other specialized tools include the trap bar or various multi-grip bars used in modern fitness settings.
