General Rules for Both Lifts
The technique known as "hooking" is permitted. It consists of covering the last joint of the thumb with the other fingers of the same hand at the moment of gripping the bar.
In all lifts, the referees must count as "No lift" any unfinished attempt in which the bar has reached the height of the knees.
After the referees signal to lower the barbell, the lifter must lower it in front of the body and not let it drop either deliberately or accidentally. He may release his grip on the bar when it has passed the level of his waist.
If a competitor cannot fully stretch his arm due to an anatomical deformation, he must report this fact to the three referees and the jury before the start of the competition.
When snatching or cleaning in the squat position, the lifter may help his recovery by swinging and rocking movements of his body.
The use of grease, oil, water, talcum or any similar lubricant on the thighs is forbidden. The lifter cannot have any substance on his/her legs when he/she arrives in the competition area. The lifter who uses a lubricant is ordered to remove it. During the removal the clock goes on. The use of chalk (magnesium) on the hands, thighs, etc, is permitted.
