Tyson Fury’s bizarre training methods have been revealed by his trainer.   

Fury will go head-to-head with Oleksandr Usyk in Riyadh, Saudi Arabia this weekend in a bid to become the first undisputed heavyweight champion of the world since Lennox Lewis.

He sustained a nasty gash above his eye during a sparring session, causing the original February date to be pushed back to May 18.

Fury has undergone a phenomenal body transformation and looks to be more lean and slim in comparison to previous fights.

Trainer Sugar-Hill Steward has revealed the Gypsy King lifts weights in the gym but has gone a step further by lighting the heavyweight’s hands on fire to help him gain an advantage over his opponents.

Sugar-Hill Steward (L) has revealed he set Fury’s hands on fire to make his knuckles stronger

‘He does, because he’s a heavyweight. But one of the things I enjoy watching him do is hit the bag, like the old-school fighters. That’s really “weights”,’ Steward told GQ when asked if Fury lifts weights.

‘You don’t see a lot of fighters actually punching the bag. They’re hitting it, but they’re not punching it properly and thinking about it like it’s their opponent. It’s [about] movement, it’s direct.

‘There are certain spots you want to hit on your opponent, and you have to have that kind of imagination when you’re on the bag – it’s about having real purpose.

‘Alongside that, at one point, I put kerosene on his hands and lit his hands on fire to make his knuckles stronger.’

Steward was then asked if he really did light Fury’s hands on fire, and responded: ‘Yeah. The kerosene burned off his hands. You’ve seen the movie, right?

The winner will unify the heavyweight division for the first time since Lennox Lewis in 1999

‘You know when the metal bones and stuff come out? His hands do that and then they regenerate skin and come back stronger and tougher.’

Similarly, Fury’s upcoming opponent Usyk revealed his brutal training regime ahead of their bout this weekend.

The Ukrainian Oleksandr told MailSport he has fought 40 strangers over 250 rounds and then broke down in tears over his dying father’s inspirational final words.
