Soviet weight lifter who won two Olympic gold medals and was the first Soviet light-heavyweight lifter to win the world championship.

While stationed at Odessa in the Soviet army, Vorobyev worked as a deep-sea diver and began weight training. As a light-heavyweight lifter at the 1952 Olympic Games in Helsinki, Fin., he attempted to jerk a world record 170 kg (375 pounds); after controversy over whether he would be charged with an official attempt after an initial drop and whether he had successfully lifted the weight on a second attempt, he had to settle for a bronze medal.

Vorobyev achieved his greatest success as a middle heavyweight. At the 1956 Olympics in Melbourne he won his first gold medal, setting a world record in the press and breaking his own world record with a lift of 462.5 kg (1,020 pounds). His greatest effort came in the 1960 Olympics in Rome, where he broke another of his own world records with a total lift of 472.5 kg (1,042 pounds). A 10-time champion of the Soviet Union, he was world champion in 1953–55 and 1957–58. Vorobyev, a medical doctor, later wrote books on weight lifting and coached the Soviet team.
