World heavyweight champion Oleksandr Usyk spoke about his approach to training.
"Wrestling, jiu-jitsu, judo, sambo - it's all great mechanics. It develops your hips, improves your striking. Because most people only have arms. I, on the other hand, practice judo and kickboxing."
Recall, December 22 Usyk won in a rematch with Tyson Fury by unanimous decision of the judges.
