A barbell is a type of exercise equipment used in weight training, bodybuilding, weightlifting and powerlifting. It consists of a long bar, usually with weights attached at each end, but can also be used without weights.
Barbells have a range in length from 1.2 metres (4 ft) to above 2.4 metres (8 ft), although bars longer than 2.2 metres (7.2 ft) are used primarily by powerlifters and are not usually seen in most gyms.
The central part of the bar varies in diameter from 25 millimetres (0.98 in) to 50 millimetres (1.96 in) (e.g., Apollon’s Axle), and is often engraved with a knurled crosshatch pattern to help lifters maintain a solid grip. Weight-plates slide onto the outer portions of the bar to increase or decrease the desired total weight. Locking Collars are used to stop plates from moving unevenly so that the lifter does not experience an uneven force.
The barbell is the longer version of the dumbbell that is used for free weight training and competitive sports, such as powerlifting, Olympic weight lifting, and CrossFit. Many exercises can be done using the barbell, such as bicep curl, bench press, Olympic weightlifting, overhead press, deadlift, and squat. Olympic barbells are usually an estimated weight of 20 kilograms (44 lb). Many fitness categories use the barbell for different reasons, for example, powerlifters use the barbell to perform compound exercise movements.
