MrBeast is paying man $250,000 to live in gym until he loses 100lbs and he's made huge change after two months

MrBeast has challenged a man to live inside of a gym until he loses 100 pounds, with a cash prize starting at a staggering $250,000.

The billionaire YouTuber, known for his extreme challenges and massive giveaway videos, is currently the most-subscribed individual (391 million) on the platform.

Aged just 26, the creator - real name Jimmy Donaldson - previously admitted he makes a staggering £550 million a year, but has 'less than $1 million (£793,000)' in his bank account because he invests it back into his videos.

Recently on Twitter, MrBeast said he is excited to share a new series of videos he's been working on, with three new challenges.

He tweeted back in March: "I have a pilot living in a $2,500,000 private jet and if he doesn’t leave for 100 days he keeps it, a cop/criminal in a jail and if they don’t leave for 100 days they win $500,000, and someone living in a gym until he loses 100 pounds for $500,000."

Now, Dexerto has got an exclusive look at the incredible new set he has built for the weight loss video.

Inside MrBeast's new gym challenge

So, the man who has agreed to do the challenge not only has access to a gym, but a personal trainer, a nutritionist, and a fully-stocked kitchen.

There's weigh-ins every month and regular challenges, one of which each completed push-up earns him an extra $1,000.

In just 30 days, he has already lost 20 pounds.

“We’re actually going to be showing you a video that might not be uploaded until 2026,” the YouTuber told the outlet.

“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.”

“By the end of the video, he might actually win over a million dollars,” MrBeast said, explaining that the contestant receives regular challenges which can increase the amount he wins.

Commenting on the new clip, however, some viewers thought the challenge seemed very doable.

One person said: "He can literally walk 12 hours per day on a treadmill while watching his iPad and have that off in three months."

Another added: "Where is the challenge? He has his own gym stocked full of machines, food, his own trainer, nutritionist AND at least 100k waiting for him at the end of the year. This is no challenge."
