“A lot of people don't believe in me. They think I'm too small for heavyweight. Just like a lot of people told me long ago that I shouldn't box. That I wasn't going to make it. I just knock my head and say I'm capable. I can do it.”

Ukrainian professional boxer

Oleksandr Usyk is a Ukrainian professional boxer. Born in 1987, he became one of the defining heavyweights of his era, and has 73 quotes on the site. Usyk was undisputed world champion at cruiserweight and later at heavyweight, a rare feat in the modern four-belt era. He was the first male boxer to become a three-time undisputed champion, and he also held the unified heavyweight title from 2021 until giving up his sanctioning body belts in June 2026. He remained undefeated when he relinquished those titles, and is still regarded as the lineal heavyweight champion.
