What is olympic weightlifting?
The sport of weightlifting consists of two lifts: the snatch and the clean & jerk. In the snatch, the weightlifter lifts the barbell from the floor to overhead in a single movement. In the clean & jerk, the weightlifter lifts the barbell first from the floor to the shoulders (the clean) and then from the shoulders to overhead (the jerk).
In a competition, each weightlifter has three attempts in the snatch and three attempts in the clean & jerk. The weight of the best of each lifts is added to create the weightlifter's total, and the best total wins.
