Swansea's Brett Johns was so poor he could not afford to travel home from the gym. So he stopped there.
As a man desperate to reach the top of MMA, there was no way he was letting a lack of money stop him from training.
"I went through a phase when I had nothing," he told BBC Wales Sport. "I couldn't afford the bus ticket home.
"I lived in the gym for the winter where there was no heating and all I had was a sleeping bag."

That might explain the outpouring of emotion when he was told he had been called up to the Ultimate Fighting Championship (UFC).
His manager filmed the video call he made to Johns and uploaded the Welsh fighter's moving reaction to Facebook.
"When I got the call, it just put me into tears," says Johns. "That seven years of hard work I've had to put in all came out in that moment.
"I'd hate to see what I'm going to be like when I win that UFC title if I'm like that when I'm getting called up."
The 24-year-old, who trains in Fforestfach, will make his debut at UFC Fight Night 99 in Belfast on Saturday.
He brings with him a record of 12 wins from 12 professional fights and is a two-time MMA world champion. Johns says the call-up was "a long time coming".
"It was very frustrating," he admitted. "I was thinking 'what more do I need to do?' Now I've achieved my dream."

Johns was not the first Welsh fighter to be signed by the UFC. That title goes to a soldier from Monmouthshire.
Jack Marshman was signed just weeks earlier in October and he will debut on the same bill as Johns this weekend. Like his Welsh counterpart, the road to the top has been a long and difficult one.
Marshman estimates he was locked up 30 times as a teenager, but joining the Tillery Combat MMA Academy in Blaina kept him "on the straight and narrow".
"I was on the wrong path," he confesses. "But without a doubt MMA changed my life. I'm not trying to be cheesy but it genuinely did.
"Instead of going out on the weekend I was training Friday night and sparring Saturday morning."
Marshman has served in the 3rd Battalion, the Parachute Regiment, for nearly a decade and he toured Afghanistan twice but the middleweight says his call-up means he will soon leave the forces to fight full time.
"You can't get any bigger than the UFC," he says, ahead of his fight against Sweden's Magnus Cedenblad. "It's the highest we can go in our sport."
Wales waited a long time for its first UFC fighter. Now two have turned up at once.
The UFC calls itself the fastest-growing sports organisation in the world and both Welsh fighters believe it will transform the sport in their home country.
"It's huge for Welsh MMA and huge for Welsh sport," says Johns. "Going back a few years, MMA in the UK was very basic. Then we had a bit of help from [Republic of Ireland's] Conor McGregor.
"They go wild about those Irish fans but the Welsh fans can be crazy as well. So I'm hoping they'll transfer from football and rugby fans into MMA."
Marshman believes it will not be long before MMA becomes as popular in the UK as boxing.
"We've already got a massive cult following," he continues. "But now it's starting to get a bit more mainstream more people are going to watch it.
"In America I think it already is [as big as boxing]. The UFC just had its first event in Madison Square Garden and that's an historic boxing venue. It just goes to show how big the sport's getting."
For Brett Johns, those cold nights in the gym will seem a long way away when he walks out to fight South Korean Kwan Ho Kwak in Belfast. The bantamweight has signed a four-fight deal, but wants to stay much longer than that.
"One of my idols was Joe Calzaghe. He fought Mikkel Kessler at the Millennium Stadium. I don't see why I can't do that too."
It was more important to be at the place he could train than the place he could sleep.

Almost 69% of code red calls were responded to within eight minutes in October, exceeding the 65% target.
Around 5% of all 999 calls were subject to the target that month, compared to 40% before the year-long trial began.
Deputy Health Minister Vaughan Gething said the new system was working, but opposition parties dispute the claim.
"We know that change can be difficult in the health service - for staff and the public," said Mr Gething.
"However, the initial figures from this pilot suggest that the new clinical response model is ensuring that patients are getting the right care, in the right place, at the right time."
Tracey Myhill, chief executive of the Welsh Ambulance Service, said: "We've made a really solid start on this ground-breaking new pilot, and today's figures are testament of that."
Welsh Lib Dem leader Kirsty Williams said she was concerned that the "vast majority" of emergency calls were no longer subject to any time-related targets or had any performance data published.
She said: "This new targeting regime may make life easier for Labour ministers, giving them one less negative headline every month, but in reality people are being left in the dark as to how well their ambulance service is actually performing."
Plaid Cymru health spokesperson Elin Jones and Ms Williams both pointed out that ambulances in three health board areas - Hywel Dda, Cwm Taf and Powys - still failed to meet the 65% threshold for code red calls responded to in eight minutes.
"The Labour government is still struggling to meet its watered-down targets," Ms Jones added.
"It is wrong of the government to call its performance a success."
The Welsh government denied Ms Williams's claim about the lack of data on non-red calls, pointing out that response data on amber calls had also been published.
Conservative shadow health minister Darren Millar congratulated the ambulance service on the figures.
"Whilst the targets are lower than those elsewhere in the UK this is a significant achievement and hardworking staff should be commended," he said.
But Mr Millar added: "The answer to sustained improvement in performance does not lie in the Labour approach of scrapping targets and record breaking NHS budget cuts; instead we need to see extra investment in the ambulance service and our wider unscheduled care system."
Ambulances in Wales have met a key time target for responding to the most life-threatening emergencies after a change to the way calls are classed.

Neil Lennon, the Norwegian's predecessor, told BBC Scotland this week he would be keen to return when Deila leaves at the end of the season.
Now Mackay, sacked by Wigan Athletic a year ago, has declared his interest.
"If Celtic wanted to talk to me, I'd certainly be keen to do that," the 44-year-old told Sky Sports News.
Former Watford and Cardiff City boss Mackay was subject to a Football Association investigation after leaving the Welsh club, when it emerged that he sent text messages containing discriminatory language.
However, the FA confirmed last year that no disciplinary action would be taken, highlighting "serious concerns about the circumstances in which particular evidence had been given and the reliability and completeness of that evidence".
Mackay recently told BBC Scotland that he wished for a quick return to club management and that Celtic was a "huge, worldwide job".
"I think the next five-year period at Celtic is a crucial one," Mackay said. "I think a record 10 titles in a row is achievable and a strong focus should be there.
"But, for that to happen, I think there is a detailed and strategic plan needed going forward. I think I could help with that and bring a fresh approach.
"I've got an understanding of the club and an ability for that to happen."
Mackay was speaking after Deila announced last week that he would stand down in the summer.
David Moyes, the former Everton and Manchester United manager sacked by Real Sociedad in November, remains the bookmakers' favourite for the job.
But the 52-year-old former Celtic defender, who is also believed to be interested in the vacancy at Aston Villa, said last week that he would be keeping his options open before making a decision in the close season.
Steve Clarke, the former West Bromwich Albion boss who was sacked by Reading last December, has had his odds slashed by one major bookmaker, who now make him third favourite behind Moyes and Lennon.
Republic of Ireland assistant Roy Keane - who had a short spell as a player with the Glasgow club and turned down the job before Deila's appointment in 2014 - has admitted he would like to return to club management, albeit he refused to talk specifically about the Celtic job,
Northern Ireland manager Michael O'Neill also opted to shun questions about the summer vacancy.

Malky Mackay has become the second high-profile former Celtic player to state that he wants to succeed Ronny Deila at the Premiership leaders.
