As an amateur, Klitschko won the super-heavyweight championship at the first World Military Games in Italy in 1995. In the same year he won a silver medal at the World Championships in Berlin, Germany, where he was defeated by Russia's Alexei Lezin in the final. In his autobiography, published in Germany in 2004, the boxer revealed that he tested positive for a banned steroid in 1996. He attributed the presence of the drug to treatment of a leg injury, but was dismissed from the Ukrainian boxing team and missed the Atlanta Olympics. His brother Wladimir moved up from heavyweight to super heavyweight to take his place in the squad and won the Olympic gold medal. His amateur record was 195–15 with 80 knockouts.
