Hemsworth put Beast and his crew through the ringer in a 30-minute conditioning circuit, designed by his Luke Zocchi, Hemworth’s personal trainer. There were nine stations, where they worked for 30 seconds of work, 20 seconds of rest. MrBeast and company suffered through loads of compound movements like sled pushes, kettlebell deadlifts, ball slams, dumbbell curl and presses, Assault bike, sandbag reverse lunges, and of course, the dreaded Ski Erg. They filtered through the room four times.

The video shows Beast and Hemsworth duking it out on Ski Erg meters, where Hemsworth wins by a few hundred calories. “I understand why he’s called Thor,” Beast says early on in the video.

Nonetheless, the crew survived, and rewarded themselves with some Mr. Beast-branded candy bars—an interesting choice of post-workout snack.

Of course, MrBeast had a few things to teach Hemsworth as a megapopular YouTuber, like how to intro a clip the best way. The pair joked as they swapped places, vamped for the camera, and shot a first-reaction video for his chocolate bar brand. By the close, Hemsworth was moving like a true content creator. We’ll see if MrBeast continues his fitness journey and starts showing up in the gym more, just like Hemsworth.
