MrBeast couple who won $350k after losing 160lbs share gruelling reality of being trapped in gym for five months

An American couple who spent five months in a gym for a MrBeast challenge have revealed the hardest mental and physical challenges they faced.

Sara Mosby and Tre Fontana spoke to LADbible about their experience with the billionaire YouTuber, following their incredible weight loss journey which was documented in the viral video.

After some eye-catching efforts, which included pulling a truck around the gym hundreds of times and climbing a rope attached to a helicopter to win more money, the two were finally able to reach and better their goal of losing 150lbs, taking 163 days to lose 160lbs (73kg) in total.

Although we see some of their most brutal exercises in the video, before they were able to get married and were reunited with their family at the end, the newlyweds have now lifted the lid on what the filming was actually like, and the things we didn't get to see in the video.

What were the biggest challenges they faced in the video?

Speaking to LADbible, Sara said: “I think, as you may have seen in the video, it was very difficult for me.

“I struggled a lot with not feeling like good enough to be in that position and not feeling capable to be in that position.”

Tre added: "For me, I think the one thing that I just struggled with was no communication with family. That was like the hardest thing being there like day to day you wake up and you're thinking about your family. I'm really close to my mum, so not being able to talk to her tell her how I'm doing or how much weight I've lost was really hard. I think that’s what I struggled the most with.”

How did they end up on MrBeast's video?

Sara, who previously worked in a desk job, was shocked when she initially got an Instagram DM from MrBeast's casting team. Fast forward a few weeks, following several rounds of interviews, and the couple would be filming with the opportunity to win a life-changing sum of money.

She explained: "It was super organic. They just found me on social media and it went from there. Within three weeks, I was working a desk job and then I was on MrBeast."

What was it like behind-the-scenes on the video?

Despite exercising every day for nearly half a year and changing their diets completely, a lot of the effort they were putting in was actually missed out from the video, with their relationship with iFit personal trainers John and Brie also vital to their success.

Sara said: “What doesn’t get shown in the video is how often we trained with John and Brie, our trainers from iFit. We trained every single day for the entire month leading up to the challenge.

“So even though we felt good physically it was still incredible taxing to train for the entire month. On challenge day, it was very mentally exhausting too because you not only have a challenge on the line but you also have a prize on the line.

"I struggled a lot mentally and emotionally and Brie did such a good job of just supporting me through it. Like they were just so much more to us than trainers.

“They became friends and mentors and like literally family. They were all that we had for five and a half months. And to this day, we talk every single day."

What is their biggest fitness advice?

Although they've had to put their honeymoon to Hawaii on hold in the months since the challenge, they haven't been too busy to continue their fitness journey, pointing out that they'd worked far too hard to give up once they hit their weight loss goal in the video.

Tre said: "That journey was too long to not continue. We did not work that hard to just go back into it. Every day we've been working out. We've gone hikes. The most important thing is to show up for yourself."

Sara added: “I think I would just say show up even if you last 10 minutes even if you do it once a week like just show up because every time that you show up I think that I've learned that you're proving to yourself that it is possible and that you are capable and their program is great we do it every single day.

"Just because we left the challenge doesn't mean that we stopped training with them. They're still our trainers and I would just say the biggest thing is just show up.

"But find what you like because if you hate it every single day, you're not going to show up. You can do so much other than just lifting weights. You can walk and go explore outside. Those are just the little changes that you can help with your health.”

What were the biggest changes they noticed after the weight loss?

Of course, the significant amount of money, and the car and truck that Tre and Sara were able to take home almost immediately following the conclusion of the challenge has been a welcome boost, but the mental and physical changes in themselves have also proven to be life-changing.

Tre said: “What changed was just how I feel about myself. What wasn't shown in the video was for a while, I think it took me about four months to realise that I actually look different. I would look at myself all the time in the mirror and I'd be like 'I look the same'. But John and Brie kept saying 'Tre, no you don’t'. I like the way I’m starting to look, so mentally I have learned to love myself a little more and give myself grace.”

Sara added: “I think for me, I did see the changes in my body, so I didn't struggle as much with that. Mine was very mental. It was just the fact that I am capable of this lifestyle and being active and I am built for it. I said a lot ‘I'm not built for this’ and I was and I am and I can continue with that mentality.”
