Later, after growing up, Foreman was known as a boxing world champion twice who was considered one of the greatest boxers in history. He had won gold at the Mexico Olympics in 1968 and began plunging into professional boxing in 1969.
He first became a heavy world champion in the WBA and WBC class on January 22, 1973 by beating TKO Joe Frazier in the second round, which made his name soar as a new star in heavyweight boxing. However, Muhammad Ali forcefully suppressed Foreman's smasher in Kinshasa, Zaire or Congo. Ali managed to disarm the title Foreman with a knockout victory in round 8 in a thrilling match.
Foreman decided to retire from boxing in 1977 following the defeat of Jimmy Young, but in 1987 Foreman returned to boxing, and surprisingly managed to knock 10 rounds of defending champion Michael Moorer in the WBA and IBF versions on November 5, 1994, so Foreman became the oldest boxer in history who succeeded in becoming a heavyweight world champion (45 years).
