Weightlifting, also called Olympic-style weightlifting, or Olympic weightlifting, is an athletic discipline in the modern Olympic program in which the athlete attempts a maximum-weight single lift of a barbell loaded with weight plates. The two competition lifts in order are the snatch and the clean and jerk. Each weightlifter receives three attempts in each, and the combined total of the highest two successful lifts determines the overall result within a bodyweight category. Bodyweight categories are different for male and female competitors. A lifter who fails to complete at least one successful snatch and one successful clean and jerk also fails to total, and therefore receives an "incomplete" entry for the competition. The clean and press was once a competition lift, but was discontinued due to difficulties in judging proper form.

The objective of the snatch is to lift the barbell from the ground to overhead in one continuous motion. The clean and jerk is a composite of two weightlifting movements, most often performed with a barbell: the clean and the jerk. During the clean, the lifter moves the barbell from the floor to a racked position across the deltoids, without resting fully on the clavicles. During the jerk the lifter raises the barbell to a stationary position above the head, finishing with straight arms and legs, and the feet in the same plane as the torso and barbell.
