Berger's IWF featherweight division standard of 60 kg (132 pounds) remained in use until 1993. His most publicized early achievement was likely his Gold medal in the 60 kg weightlifting competition at the
1956 Melbourne Summer Olympics, setting a world record of 352.5 kilograms (776 lbs) for three lifts. Four days before competing for the featherweight (60 kg) title at the
1960 Rome Summer Olympics, he broke four world records in the press (264 pounds), the snatch (253 pounds), the clean and jerk (336 pounds), and the total (853 pounds). Ike believed the strain and injury caused by this effort was the reason he won only a Silver Medal behind Eugene Miniev of the Soviet Union in Olympic competition. Berger became known as one of the few athletes who could compete against the Soviet dominance in weightlifting in his featherweight (60 kg) weight class. Later in his career, demonstrating his consistency in high level international competition, he won a silver medal at the
1964 Tokyo Summer Olympics at 60 kg. == World championships ==
