Peter Fury, father and head trainer of heavyweight contender Hughie Fury, says he put his son through hell in training camp.
This Saturday night, at the O2 Arena in London, Fury will face one of the toughest opponents of his career, former world champion Alexander Povetkin.
The contest will take place as part of the Vasiliy Lomachenko vs Luke Campbell lightweight title clash.
Fury recently signed a co-promotional agreement with Eddie Hearn of Matchroom.
He wants to make a big statement in the fight to place himself in the mix with the biggest names of the weight class.
In order to make that statement, Fury went through one of the toughest camps of his career.
"In this one, he's working on a lot more punch output. Interval training for speed, to get the heart rate as high as he possibly can, and drop it down quick. It's going to be intense and he's got to be prepared to let his hands go, and maybe five, six, seven shots got at a time," Hughie Fury told Sky Sports.
"He's with [strength and conditioner] Kerry Kayes three times a week, so we alternate the days. Since we've had Kerry on board, he's been absolutely brilliant. What he's done with his physique, his body fat and everything else. Does all his dietary requirements. He's totally recovered from [his past health issues], he's got no issues at all now. His diet is very simple, very clean food. Lots of vegetables, no additives. Eat healthy, plenty of it.
"He'll spar between anything from 12-20 rounds. I want him to be comfortable in there. This is his living, it's his eat, sleep, drink. He's got to be at home in there as much as he is out of the ring. He can take rounds off. He can do what he wants, he can slip and slide, and not do much. He's got to get super comfortable in there. Whatever the outcome, he can do those rounds."
