WBC, WBO and IBF light heavyweight champion Artur Beterbiev published a motivational post on Instagram.
"The most important principle in my life - if you are engaged in any business, you just have to give yourself to it 100%. If I'm training, I have to give my best in training. This principle is my guideline in everyday life as well. No matter what I do, I will still demand full commitment from myself. It may seem too much for some, but I expect the same from the people around me," Beterbiev wrote.
Beterbiev is expected to fight a unification bout against Dmitry Bivol on June 1 in Riyadh, Saudi Arabia.
