Oleksandr Usyk is making some tweaks to his usual preparation for a fight.

The unified WBO, WBA, IBF, and IBO heavyweight champion from Ukraine is in deep talks to fight WBC titlist Tyson Fury of Manchester, England, for the undisputed heavyweight championship. April 29 has been identified as the target date, and London's Wembley Arena is the preferred venue. The fight is far from a done deal, as the organizers are in disagreement over compensation.

Usyk, a former undisputed champion at cruiserweight, is coming off two consecutive wins over Anthony Joshua. In both fights, Usyk, who stands six-foot-three, weighed in at a career-high of 221 pounds in order to better compete with the hulking Joshua, who is six-foot-six and routinely weighs around the 240-pound range.

In Fury, Usyk will face an even bigger opponent. Fury is six-foot-nine. For his last fight with Derek Chisora in December, Fury weighed in officially at 268 pounds. Eight months earlier, in his fight with Dillian Whyte, Fury weighed 264 pounds.

With Fury’s size in mind, Usyk is tailoring his training camp accordingly. He has even suggested he may come in a bit heavier than usual.

“There will be changes in the strategy for the fight, but I’ll continue to prepare in the same way,” Usyk said on The Overlap. “I’ll do a lot of training, swimming, running, boxing.

“There will be new workouts because the guy (Fury) is slightly different. He is big and tall. So, his combinations and boxing style will be different. There won’t be any less work to do. If anything, there’ll be more of it. I will gain the necessary weight to do my job properly.”

Asked if he thinks Fury is a more difficult fighter than Joshua, Usyk answered in the affirmative.

“Yes, of course,” Usyk said. "He has a different style. Fury is more audacious.”  

Usyk also offered a breakdown of his training regime, which is known to be particularly arduous, even by elite prizefighting standards.

“The first workout is at 5 AM. Mostly, it’s cardio. Then at noon, there is a second workout. If it’s in a swimming pool, then I swim at least 2 kilometers in the pool. The main training session is at 6 PM. On Mondays, Wednesdays, and Fridays, we have sparring sessions. On Saturday, as you have seen today, I run for 10, 15 or 20 kilometers. Sunday is my day off which I dedicate to praying and going to church.”
