Clean and jerk
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 deltoids and 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.
Of the several variants of the lift, the most common is the Olympic clean and jerk, which, with the snatch is contested in Olympic weightlifting events.
Clean
To execute a clean, a lifter grasps the barbell just outside the legs, typically using a hook grip. Once the barbell is above the knees, the lifter extends explosively, raising the bar as high as possible before quickly dropping into a squat and receiving it in a "racked" position in front of the neck and resting on the shoulders. To complete the clean, the lifter stands, often propelling the bar upward from the shoulders slightly as the erect position is attained and shifting the grip slightly wider and the feet slightly closer together in preparation for the jerk.
