The Olympic lift that moves a barbell from the floor to overhead in one continuous motion is the snatch.
In the snatch, a lifter uses a wide grip to pull the bar from the platform, accelerates it upward with powerful extension of the hips, knees, and ankles, and quickly moves under it. The bar is caught overhead with straight arms, often in a deep squat, before the lifter stands fully upright. The defining feature is that the bar travels from floor to overhead without stopping at the shoulders.
The snatch is one of the two lifts contested in Olympic weightlifting; the other is the clean and jerk. In the clean and jerk, the athlete first brings the bar to the shoulders in the clean, pauses in the front-rack position, and then sends it overhead in the jerk. That two-stage sequence is the key distinction between the lifts.
The full squat snatch is the standard competition version, but power snatches and other variations are common in training. The lift demands speed, balance, mobility, timing, and precision because the athlete must pull high enough to get under the bar while keeping it stable overhead.
