 until 1972. It was removed from Olympic weightlifting due to difficulties in judging proper technique.

The clean and press technique consists of the two main movements of which it is named.

Clean phase

After taking a big breath and setting the back, the lifter jumps the bar up through triple extension (in very quick succession) of the hips, knee
Knee
The knee joint joins the thigh with the leg and consists of two articulations: one between the fibula and tibia, and one between the femur and patella. It is the largest joint in the human body and is very complicated. The knee is a mobile trocho-ginglymus , which permits flexion and extension as...

s and then ankle
Ankle
The ankle joint is formed where the foot and the leg meet. The ankle, or talocrural joint, is a synovial hinge joint that connects the distal ends of the tibia and fibula in the lower limb with the proximal end of the talus bone in the foot...

s. When the legs have driven the bar as high as possible, the lifter pulls under the bar by violently shrugging (contracting) the trapezius muscles of the upper back ("traps") dropping into a deep squat position and spinning the hands around the bar so the elbows are extended in front.

At the same time, as the arms are brought up with the elbows extended in front of the chest so the bar may now lay across or "rest" across the palms, the front of the shoulder
Shoulder
The human shoulder is made up of three bones: the clavicle , the scapula , and the humerus as well as associated muscles, ligaments and tendons. The articulations between the bones of the shoulder make up the shoulder joints. The major joint of the shoulder is the glenohumeral joint, which...

 or deltoid muscle
Deltoid muscle
In human anatomy, the deltoid muscle is the muscle forming the rounded contour of the shoulder. Anatomically, it appears to be made up of three distinct sets of fibers though electromyography suggests that it consists of at least seven groups that can be independently coordinated by the central...

s, and the clavicle
Clavicle
In human anatomy, the clavicle or collar bone is a long bone of short length that serves as a strut between the scapula and the sternum. It is the only long bone in body that lies horizontally...

s. At this point the lifter should be in a full squat position, with his buttocks on or very close to the heels, sitting erect with the bar resting comfortably across the deltoids and fingers. By keeping a rigid torso and maintaining a deep breath hold the bar bends over the lifter's clavicle.

The improvement in construction of modern weightlifting bars has greatly increased this springing action compared with bars used in the first half of the twentieth century. This springing action is used to rebound from the full bottom squat position. This is commonly known as a front squat.

Press phase

Once the bar is on the anterior deltoids, the lifter proceeds to pressing the weight overhead. During the Olympics, many lifters lie back while pressing. This allowed for more weight to be pressed. Vasiliy Alekseyev
