Weightlifting (often known as Olympic weightlifting) is a competitive strength sport in which athletes compete in lifting a barbell loaded with weight plates from the ground to overhead, with the aim of successfully lifting the heaviest weights. Athletes compete in two specific ways of lifting the barbell overhead. The snatch is a wide-grip lift, in which the weighted barbell is lifted overhead in one motion. The clean and jerk is a combination lift, in which the weight is first taken from the ground to the front of the shoulders (the clean), and then from the shoulders to over the head (the jerk). The sport formerly included a third lift/event known as clean and press.
Each weightlifter gets three attempts at both the snatch and the clean and jerk, with the snatch attempted first. An athlete's score is the combined total of the highest successfully-lifted weight in kilograms for each lift. Athletes compete in various weight classes, which are different for each sex and have changed over time.
Weightlifting is an Olympic sport, and has been contested in every Summer Olympic Games since 1920. While the sport is officially named "weightlifting", the terms "Olympic weightlifting" and "Olympic-style weightlifting" are often used to distinguish it from the other and events that involve the Weightlifting, such as powerlifting, weight training, and strongman events. Similarly, the snatch and the clean and jerk are known as the "Olympic lifts".
While other strength sports test limit of strength, Olympic-style weightlifting also tests limits of human power (explosive strength): the Olympic lifts are executed faster, and require more mobility and a greater range of motion during their execution, than other barbell lifts. The Olympic lifts, and their variations (e.g., power snatch, power clean) as well as components of the Olympic lifts (e.g., cleans, squats) are used by elite athletes in other sports to train for both explosive strength (power) and functional strength.

To perform the clean, the lifter takes a shoulder-width grip on the bar and pulls it off the floor, and then rapidly re-bends their knees (and bends their arms) to get their body under the barbell and "catch" the bar on the front of the shoulders (usually in a deep front squat position). The lifter finishes the clean by rising to a standing position while holding the barbell on the front of their shoulders. The lifter then uses the jerk to jump into a bent knees position (most commonly with one foot forward and the other back, a technique known as the split jerk) while pumping the barbell overhead . The jerk is completed when the lifter re-straightens the legs (bringing them together after a split jerk) so they come to a straight standing position with the barbell held overhead.
A third lift, the clean and press, was also a competition lift from 1924 through 1972. It entails a clean followed by an overhead press. The overhead press is distinguished from the jerk, in that jerking movements, bending of the legs, and displacement of the feet are prohibited. It was discontinued after 1972 due to difficulties in judging proper form.

During competition, the snatch event takes place first, followed by a short intermission, and then the clean and jerk event. There are two side judges and one head referee who together provide a "successful" or "failed" result for each attempt based on their observation of the lift within the governing body's rules and regulations. Two successes are required for any attempt to pass. Usually, the judges' and referee's results are registered via a lighting system, with a white light indicating a "successful" lift and a red light indicating a "failed" lift. This is done for the benefit of all in attendance, be they athlete, coach, administrator, or audience. In addition, one or two technical officials may be present to advise during a ruling.
Lifters who fail to successfully complete at least one snatch and at least one clean and jerk fail to total, and receive an "incomplete" entry for the competition.
In 1896, the inaugural Olympic Games in Athens included weightlifting in the field event (the predecessor to today's track and field or athletics event). In the early Olympic Games, a distinction was drawn between lifting with 'one hand' only and lifting with 'two hands', and all competitors competed together regardless of their size and weight. The winner of the 'one hand' competition in 1896 was Launceston Elliot of Scotland, while the winner of the 'two hands' event was Viggo Jensen of Denmark.

Further World Weightlifting Championships followed in 1898 in Austria, 1899 in Milan, and 1903 in Paris, with the International Weightlifting Federation being founded in 1905.
Weightlifting was next contested at the Olympics in the 1904 Games (again in athletics), and at the 1906 Intercalated Games, but was omitted from the Games of 1900, 1908 and 1912 (1912 being the last Games until after the First World War).
The 1972 Olympics was the last Olympics featuring the clean and press, as difficulties in judging proper form led to it being dropped from subsequent competitions. Athletes, rather than "strictly" pressing the weight overhead with an upright torso, had been using their hips and leaning backward substantially. Some athletes were able to initiate the press with a hip thrust so rapid that judges found it difficult to determine whether or not they had utilized any knee bend to generate additional force, something strictly prohibited in the rules. Also prohibited was "excessive layback" (leaning back too much), but it was considered too difficult to determine what degree of layback constituted a rule violation. As a result, the clean and press was discontinued as a competition lift after 1972.
In 2011, the International Weightlifting Federation (IWF) ruled that athletes could wear a full body "unitard" under the customary weightlifting uniform. Kulsoom Abdullah became the first woman to do so at the U.S. National Championships that year, and athletes are allowed to do so at the Olympics. IWF rules previously stated that an athlete's knees and elbows must be visible so officials can determine if a lift is correctly executed.
A men's Olympic barbell weighs 20 kg (44 lbs) with a shaft diameter of 28 mm and a length of 2200 mm, whereas a women's Olympic barbell weighs 15 kg (33 lbs) and has a shaft diameter of 25 mm with a length of 2010 mm. The distance between the sleeves, however, is the same for the men's and the women's bars at 1310 mm. The grip texture of the bar is called the knurling, and is distributed differently between the men's and women's bars: the men's has knurling in the center but the women's does not. The Olympic barbells used in competition are certified by the IWF.
Olympic lifters also tape their wrists, preventing exaggerated and uncomfortable joint movement during lifts. For particularly heavy overhead lifts, a taped wrist enables the lifter to regulate wrist extension and delimit the translation of the radius and ulna distal heads. However, while taped wrists can prevent wrist and forearm injuries in the short-term, excessive use can lead to weakened connective tissue in the area, increasing the risk of pain and injury.
There are also different heel constructions. Most modern Weightlifting shoes use a hard TPU plastic heel that does not deform and is more durable than other materials. However, there has been a resurgence in premium shoes using retro wood heels which are hard but do not last as long.
Knee sleeves
Some weightlifters may use knee sleeves to provide joint support and assist in standing from the deep squatting position.
Wrist wraps
Wrist wraps are commonly used to provide support to the joint.
