General Rules for All 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 both 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. The grip on the bar must only be released when it has passed the level of the shoulders.
An athlete, who, for any reason, cannot fully extend the elbow(s), must report/display this fact to all on-duty Referees as well as the Jury prior to the start of each lift. This is the sole responsibility of the athlete.
When snatching or cleaning in the squat style, the athlete may assist their recovery by swinging or rocking their body while in the squat position.
The use of chalk (magnesium carbonate) is permitted.
The use of grease, oil, water, talcum or any other lubricant(s) on the athletes thighs is forbidden. An athlete who uses forbidden lubricant(s) is orgered to remove it immediately. If during removal the clock is running for that athlete, the clock remains running.
