YouTuber MrBeast is subscribing, liking and commenting on his latest fitness journey.

The social media star, whose real name is Jimmy Donaldson, recently shared insight into his workout routines, posting before-and-after shirtless images of his gym transformation.

"Woke up and realized I was obese so I started lifting and walking 12,500 steps a day," MrBeast tweeted on June 29. "Still got a long way to being yoked but I'm happy with my progress so far."

The 25-year-old received support from fans in the comments, including one user who wrote, "This is inspiring AF makes me want to get into better shape thank you for this push man and congrats." In response, MrBeast sent back a heart emoji.

When another user praised his progress but remarked that his pecs "need work," MrBeast replied, "Everything needs work, step one was not be fat haha. Now we get big."

In addition to grinding on his fitness journey, MrBeast—who boasts more than 163 million YouTube subscribers—pours his time into creating content for his social media pages.
