Jimmy ‘MrBeast’ Donaldson gave us a behind-the-scenes look at the massive set he built for a video that he’s been filming for months.
Back in March 2025, MrBeast revealed a series of new videos he is actively filming for his massive YouTube channel in a post on X.
One of those ideas involved a man living inside of a gym until he loses 100 pounds, but he hadn’t given fans any more details since that tweet.
During a visit to MrBeast’s compound in January 2025, Dexerto got an exclusive, behind-the-scenes look at the set he’d created for this weight loss video.

During our chat MrBeast, he gave us a walkthrough of the set, which he allowed us to record. In our tour, you can see all the equipment that the man living in the gym has access to, which includes dozens of weight-lifting setups and cardio machines.
“We’re actually going to be showing you a video that might not be uploaded until 2026,” MrBeast said. “If you’ve ever seen any one of my videos, you’ll know that giant red circles mean death. AKA, if you step on it, you’re eliminated. Inside this giant circle is a gym, and one of my friends who’s been in here for months.”
According to the YouTuber, the man – who is one of his friends – could earn a major cash prize that initially started at $250K… but the contestant receives a challenge every month that could increase the amount he wins.
“By the end of the video, he might actually win over a million dollars,” MrBeast added.
He’s not doing it alone, either. The contestant has access to a fully stocked fridge, a nutritionist, a trainer and “every single” exercise machine he may need. In the first 30 days of being locked inside the circle, he lost 20 pounds.
It’s unknown when the video will be uploaded, as it’s all dependent on how long it takes the man to hit the goal of 100 pounds lost.
This isn’t the only wild video idea the YouTuber has had lately, either. In April 2025, Donaldson went viral after joking about gathering 100 men to go up against a single gorilla, to settle the debate on which side would win.
