Rules for the Clean and Jerk
The first part, the Clean:
The bar is centered horizontally on center of the competition platform. The athlete takes the start position in front of the barbell by grabbing the barbell and bending the knees. The barbell is gripped, palms downwards and pulled in a single movement from the platform to the shoulders, while either splitting or bending th legs. During this continuous movement upward the barbell remains close to the body and the barbell may slide along the thighs. The barbell must not touch the chest before it stops at the final position either on the clavicles, chest or on fully bent arms. The athlete's feet must return to the same line and the legs must be fully extended before starting the Jerk. No part of the body other than the feet may touch the platform during the execution of the Clean.The athlete may recover in his/her own time and must finish with the feet on the same line and parallel to the plane of the trunk and the barbell.
The second part, the Jerk:
The athlete must become motionless after the Clean and before starting the Jerk. The athlete bends and extends the legs simultaneously as the arms move the barbell upward in one motion to the full extent of the arms. The athlete returns his/her feet to the same line parallel to the plane of the trunk and the barbell with his/her arms and legs fully extended. The athlete waits for the Referees' signal to replace the barbell on the competition platform.
The Referees give the signal to lower the barbell as soon as the athlete becomes motionless in all parts of the body.
Before the Jerk, the athlete may adjust the position of the barbell for the following reasons:
a) to withdraw or "unhook" the thumbs b) if breathing is impeded c) if the barbell causes pain d) to change the width of the grip
The barbell adjustments noted above are not considered to be an additional attemps at the Jerk.
Incorrect movements for the Clean
Placing the bar on the chest before turning the elbows. Touching the thighs or the knees with the elbows or the upper arms.
Incorrect movements for the Jerk
Any apparent effort of jerking which is not completed. This includes lowering the body or bending the knees. Any deliberate oscilation of the barbell to gain advantage. The athlete and the barbell have to become motionless before starting the jerk.
