=== Olympic Games 1920–1972 ===
In [[Weightlifting at the 1920 Summer Olympics|1920, weightlifting returned to the Olympics]] and, for the first time, as an event in its own right – and weightlifting has been contested at every (summer) Olympics Games since. The 1920 Games took place at Antwerp in Belgium; and fourteen nations competed. The competition lifts were the 'one hand' snatch, the 'one hand' clean and jerk and the 'two hands' clean and jerk. At the next Olympic Games, [[Weightlifting at the 1924 Summer Olympics|in Paris, in 1924]], the 'two hands' press and the 'two hands' snatch were added to the program, making a total of five lifts; and weight classes were introduced for competitors, with weightlifters competing in five weight divisions.[[File:RIAN archive 484445 Winners of the weightlifting competition in the 1980 Olympics.jpg|thumb|The 110 kg division weightlifting winners at the [[Weightlifting at the 1980 Summer Olympics – Men's 110 kg|1980 Summer Olympics]], held in [[Moscow]]]]
[[Weightlifting at the 1928 Summer Olympics|In 1928]], the sport dropped the 'one hand' exercises, going forward with three 'two hand' exercises: the ''snatch'', the ''clean and press'', and the ''clean and jerk''.

The [[Weightlifting at the 1972 Summer Olympics|1972 Olympics]] was the last Olympics featuring the ''clean and press'', as difficulties in judging proper form led to it being dropped from subsequent competitions. Athletes, rather than "strictly" pressing the weight overhead with an upright torso, had been using their hips and leaning backward substantially. Some athletes were able to initiate the press with a hip thrust so rapid that judges found it difficult to determine whether or not they had utilized any knee bend to generate additional force, something strictly prohibited in the rules. Also prohibited was "excessive layback" (leaning back too much), but it was considered too difficult to determine what degree of layback constituted a rule violation. As a result, the ''clean and press'' was discontinued as a competition lift after 1972.
