As shown by its name, weightlifting refers to competitions in which competitors lift heavy barbells. The competitor who lifts the heaviest weight wins a competition. Competition methods comprise the Snatch and the Clean and Jerk. Competitors are classified by bodyweight, into 10 categories for men and 9 categories for women.
Competitors decide and declare the weight they are to lift for themselves.
For both the Snatch and the Clean and Jerk, a competitor has only 3 attempts to lift the barbell. The Snatch is an event in which a lifter must lift a barbell above the head in one movement with the arms completely straight.
