Olympic Weightlifting consists of the disciplines of "Snatch" and "Clean & Jerk". The two disciplines are divided into the three movement complexes snatch, implementing and expelling. These are presented below:
Snatch
Positionen im Reißen 1 bis 6 (Oehler & Patzke, 2019, S. E-3)
The barbell lies horizontally in front of the legs of the lifter. It is gripped with the palms of the hands down and brought in a single movement from the floor to the high stretch with outstretched and vertical arms, either with a lunge or bending both legs (squat). The dumbbell is to be guided upwards along the body in a continuous movement. During the experiment, no part of the body other than the feet may touch the floor.
The lifted weight must be fixed in the final position with legs stretched, feet on the same line and arms stretched until the referee's signal to remove the weight. The wrists should only be turned after the barbell is above the head height of the lifter. A lifter can remain at a standstill or crouch at its own discretion. The judge's sign to put down the barbell must be given as soon as the lifter's body is motionless.
Clean & Jerk
"C&J" is officially referred to in the rules and regulations as "Clean & Jerk". It consists of two partial processes, moving the barbell onto the shoulders and pushing the barbell out over the head, which is its main difference from tearing.
Clean
The barbell lies horizontally in front of the lifter's feet. It is gripped with the palms of the hands and brought from the floor to the shoulders in a single movement, either with the lunge or with the cropping technique. The barbell must not touch the chest before the final position; it should rest on the collarbones, chest, or fully bent arms. The lifter can remain in this position as it sees fit. However, when crouching, the elbows must never touch the thighs, otherwise the attempt is invalid.
Jerk
Bending and stretching the legs and arms to bring the dumbbell up to the stretch with fully stretched, vertically standing arms (non-stop upward movement), then adopting the basic position, legs and arms are stretched, wait until the referee's signal to remove the dumbbell. The signal must be issued as soon as the lifter is absolutely motionless.
The dumbbell must be at rest before pushing it out, "tipping" makes the attempt invalid. Likewise, the expulsion must be carried out in a single movement up to the extended arms, a visible pressing with at least one arm also invalidates the attempt.
