by the lifter rising to a standing position whilst holding the barbell overhead. The snatch demands precise balance. The clean and jerk is a combination lift, in which the athlete gets the barbell overhead in two stages: first by lifting the barbell into support on the front of the shoulders (the clean), and then lifting it from shoulders to overhead (the jerk). 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 whilst 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) whilst 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. Weight classes Athletes compete in a division determined by their body mass. In summer 2018, the IWF approved the current weight categories, specifying which 7 of the 10 total would be contested at the 2020 Summer Olympics. IWF Men's weight classes: Categories and over (240 lb+) Only five weight classes were chosen for Paris 2024: 61 kg, 73 kg, 89 kg, 102 kg and over 102 kg. IWF Women's weight classes: Categories and over (192 lb+) Weight classes chosen for Paris 2024: 49 kg, 59 kg, 71 kg, 81 kg and over 81 kg. Official procedure In each weight division, lifters compete in both the snatch and clean and jerk. Prizes are usually given for the heaviest weights lifted in each and in the overall—the maximum lifts of both added. The order of the competition is up to the
