Boxers, Muay Thai fighters and submission grapplers all use the busy, authentic MMA gym which is tucked away on an industrial estate.

In a side room filled with bags and rings, Jack Catterall parks himself on a ring apron, wraps his own hands and chats away with anybody and everybody.

The 32-year-old has spent the past few months at the gym training under former world title challenger, Stephen "Swifty" Smith, and the gym’s founder, John Gillies.

Russ Anber, a 2026 International Boxing Hall of Fame inductee, is also on hand to add his input.

As The Ring’s No. 10 welterweight hits the pads and body-belt, amateurs and keep-fitters run through Thai boxing drills and well known fighters flit in and out to say hello and watch.

Saturday, Catterall (32-2, 14 KOs) will find himself in entirely different surroundings. He will fight Shakhram Giyasov (17-0, 10 KOs) for a WBA 147-pound belt in the shadows of the Great Pyramids of Giza in Egypt.

The busy, business-like atmosphere seems to suit Catterall perfectly.

“It's just a great environment to be in. There's a lot of different characters,” Catterall told The Ring.

“You’ve seen the sign. There’s no egos, everybody's helping each other. You should see it at night time. There's a hundred amateur fighters in this gym. There's 26 coaches. It's unbelievable. Everybody's just pushing each other.”

Four Corners is Catterall’s third boxing home in under a year.

After spending years with Jamie Moore in Manchester, Catterall crossed the Atlantic and trained with Bozy Ennis in Philadelphia for his 11th-round stoppage of Ekow Essuman in November.

After the fight, he returned to his Chorley home and continued to tick over at Four Corners whilst he waited for a new date. Things went so well that when the fight with Giyasov was offered, Catterall decided not to change things.

“I spoke to Bozy and he's really cool,” Catterall said.

“The door's always open over there but I said, 'I'm over here. My feet are on the ground. I've got a fight coming up.'

“He wished us all the best and I'm over the moon with Stephen and John."

Catterall’s time in "Bozy’s Dungeon" may have been brief but it more than served its purpose.

The strong, clever southpaw will always rely on his mastery of range and his ability to control the pace of a fight but during his early rise though the ranks he was also known for his ability to ruthlessly accelerate through the gears and hurt people.

Over the years, that edge dulled. A prolific sparrer and a smart fighter, Catterall developed an effective way of controlling rounds and winning fights.

Being in a different habitat with a group of hungry strangers shook him out of his comfort zone. In a way it acted as a reset button.

“I found myself in a position where maybe things were getting monotonous, a bit too comfortable, a bit too casual. I needed my back to be against the wall. I needed to find that fire and that's exactly what I did,” Catterall said.

“I got away, found that, and I'm over here now. I find myself in that position again now. I've got a fire in my belly and I'm training hard. I'm training good.

“People say different things but I think when you spend so much time with certain coaches, maybe we get a bit too comfortable.

“For me, in the space of a year now, I've been over to America. I’m training in Liverpool. I'm in this gym where there's a lot of different coaches in and out the gym and I'm seeing new things. I'm learning. I'm never going to change my style drastically, but every day I'm trying those one percents. I'm trying to improve and get better and I feel like I am doing, still at 32.”

Catterall is enjoying learning again.

Being around so many different disciplines has opened his mind. Before training, he and Gillies discuss the underrated effectiveness of leg kicks and after the fight with Giyasov, he plans to start taking wrestling classes and eventually try his hand at mixed martial arts.

The cage and mats will have to wait. For the time being, Catterall and his team are piecing together a strategy to beat Giyasov.

Smith was a skillful fighter who is forging a reputation as one of the sport’s smartest up and coming trainers whilst Gillies is a veteran of combat sports. He has spoken of his ambition to make Four Corners the only gym in the world to have boxing, Muay Thai and UFC world champions under the same roof.

“If you look at my style, I feel very comfortable fighting in the pocket and John's fighting style was similar, using the frames, using the angles, throwing short punches,” Catterall said. "It's not too dissimilar to stuff that I do but on top of that, adding other stuff to the game.

“I went away for the reset. I got that and I had that fire in my belly and I got the performance I needed last time and I'm trying to build on that now. Not just winning the rounds but having those big moments in the rounds, cementing myself and going through the gears.”

Catterall will certainly need different dimensions, looks and strategies if he is to get past Giyasov.

The Uzbek is a former amateur World Championship gold-medalist and he won a silver at the 2016 Olympic Games. The 32-year-old has been inactive and hasn’t boxed anybody of Catterall’s level.

Catterall knows just how much is at stake this weekend and has done his research.

“It's a brilliant fight on paper,” he said. “He's undefeated. He turned pro in 2016. He had a massive amateur pedigree. He's been out of the ring for a year. On the flip side, he's boxed six southpaws.

“You can over-analyze it, but for me, it's a brilliant fight. It puts me in a great position. It's for the WBA regular world title and a massive belt.

“I'm pumped up for it. Looking at his style, looking at how he fights, it didn't take me long to work out the patterns. The stuff that I have seen, I think, 'You know what? Brilliant. Come and try and do that.'"
