The clean and jerk is one of the two snatch).

The clean portion of the lift refers to the lifter explosively pulling the clavicles. In early twentieth century weightlifting competitions, a variant movement called the "Continental" (because it was practiced by Germans rather than the British) allowed the lifter to pull the barbell up to his belt, where it could rest. Then with several successive flips, the bar would be moved up the torso until it reached the position for the overhead jerk. The Continental gained a reputation as clumsy, slow, and nonathletic compared to the swift coordinated movement required to lift the bar "clean." Hence, the clean movement was adopted by the early weightlifting federations as the official movement.

[edit] Movement

[edit] Beginning

An Iraqi weightlifter with 180 kg (397 lb) in the rack position; at the end of the clean phase.[1]

The chest is up and the back is neutral to slightly hyper extended. This is the starting position of the "pull" phase of the lift.

[edit] Clean phase

The lifter jumps the bar up through front squat position. The lifter then stands in preparation for the second phase.

Position after an overhead split jerk.

[edit] Overhead jerk phase

From the standing position, the lifter bends the knees and then straightens them in order to propel the barbell upwards. The lifter pushes slightly with the arms. This pushes the lifter underneath the barbell. A split jerk is most often used, in which one leg lunges forward while the other moves backward. The lifter must hold the barbell overhead, keep the arms locked, and move the legs directly underneath the torso so that the entire body lines up in a single plane. A push jerk can also be used, in which the lifter keeps both legs in position, bends the knees and jumps into lockout position.

[edit] Variants

Variants of the jerk include the old style jerk where the legs stay under the lifter's hips and the lifter squats down under the bar and then stands upright. The main advantage of the split jerk is that it is easier to balance the bar forwards and backwards whereas the main advantage of the more difficult squat jerk is a greater ease of recovery.

The power clean, a weight training exercise not used in competition, refers to any variant of the clean in which the lifter does not catch the bar in a full squat position (commonly accepted as thighs parallel to the floor or below). The hang clean, another weight training exercise, begins with the barbell off the ground arms hanging down. I.e., any position between the barbell touching the ground and the body fully erect. Both power and hang cleans are considered to be ideal for sports conditioning; as they are both total body exercises, that have been known to increase neuromuscular co-ordination and core stability.
