India, Aug. 19 -- YouTube star Jimmy "MrBeast" Donaldson has confirmed plans for another extreme fitness challenge, just months after releasing his viral weight loss video. The new project comes after the YouTuber spent a staggering $5.5 million on his previous experiment, where participant Majd Khader lost 100 pounds in six months.

In June 2025, MrBeast uploaded a video that showed Majd locked inside a custom-built gym for half a year. The transformation was a massive success, with Majd walking away with $417,650 in prize money.
