Kiwi boxers David Nyika and Joseph Parker sit down for a Zoom interview at their apartment in Morecambe, North West England. They look absolutely exhausted.
"That was probably one of the hardest workouts I've ever done," Nyika gasps.
They've just completed what they call 'F-you Friday'.
"It's 15 rounds of work," trainer Andy Lee explains. "It's a mix of bag drills, pads and body bag work.
"Also there were two rounds of wrestling, so David and Joe were both wrestling with Tyson today.
"I was lucky, I was in with the featherweights," he smiles.
That's Tyson Fury - WBC heavyweight world champion. Nyika and Parker are training alongside him, as they prepare half-brother and reality TV star Tommy Fury for his 'superfight' with social media star Jake Paul next month.
They've formed a stable of boxers that Nyika, 26, describes as "the best in the world", all training for major fights together.
The sessions are relentless and the whole team watches on. For the rookie pro - who is embarking on a run in the cruiserweight division - it's a shock to the system for someone who has spent his entire amateur career training by himself.
"Out of the corner of my eye, I’ll see Tyson watching me train," says Nyika. "I know all the time, if I start slacking, he'll be right up my butt.
"It's intense. I'm so competitive, I won't let that get to me and I'll pull my weight - people don't see me fold."
That intensity from Fury and the high standards he commands were evident from his very first meeting with Nyika.
"The first day I was in the gym at the same time as him, he laid it all on me," says Nyika. "He told me everything I was doing wrong, everything that was - in his words - 'shite'.
"It was pretty confronting."
Nyika has joined compatriot Parker and the rest of the UK crew to prepare for his second pro fight, as Parker lines up another clash with rival Derek Chisora on the same December 19 (NZ time) card at Manchester.
For Parker, who's crafting his own journey to become two-time world heavyweight champion, having another Kiwi in camp is refreshing.
"It's great to have Dave here," he says. "He's a great training partner, he's very fit, he's a student of the game, and he's making the most of the opportunity to train here with Andy and Tyson."
Trainer Lee is in the kitchen, feeding his hungry boxing housemates. As hard as they work in the gym, away from boxing, everyone is relaxed and in a good space.
The relationship Lee, Nyika and Parker share, living, and training together, is special.
"We still work as a team, even though they're individuals," says Lee. "People who suffer together have bonds.
"These guys are suffering together every day, so it's inevitable they're going to have a tight bond."
After claiming a bronze medal at the Tokyo Olympics, Nyika knew he had to keep active, and planned to link up with Parker and Lee. He hasn't looked back and has earned praise from everyone, including the Furys.
"He's a pleasure, he's a lovely young man," says Lee. "He’s fitting in like he's always been here.
"As a boxer, he's very much ingrained in the amateur style. It's a long term project in terms of what he can be as a professional, but there's a huge potential there."
That potential has caught the eye of 'The Gypsy King' personally and the relationship among the group is growing with every week that passes. Social media videos show Tyson and father John out to dinner with Nyika and Parker, where they end up singing a rendition of 'Sweet Caroline' at the top of their voices.
But when it comes to training, it's time to focus and everyone knows it. As someone who’s climbed to the top of the boxing world himself, Parker offers a unique perspective on what his countryman is going through.
"Dave's in a great position, because not only can I give him advice, but he's got Andy, he's got Tyson, [Irish middleweight] Jason Quigly... the whole team.
"He's had one pro fight and everyone here is giving him advice. He knows how important it is to make a statement, he knows how important it is to be ready.
"It's a big stage for him to be on and he is making the most of it."
Lee admits taking Nyika from the amateur ranks to a professional contender will be a challenge, but one the whole group is excited about.
"He's still got some fundamental mistakes he makes, but he's made improvements already. I think Tyson's seen that and he’s kind of embraced them a little bit."
Says Nyika: "It's been an epic few weeks. I'm just starting to realise how special this group is and I'm privileged to be part of a special camp.
"Everyone's been so forthcoming, the Fury's treat me as one of their own. I feel like this is the best environment for me to build."
