Performing muscle-ups requires explosive power and can be a challenging feat for adults, even those who were proficient as teenagers.

“I actually just started doing muscle-ups again like a couple months ago in in my little home gym and I was like I haven't done a muscle up since I was a teenager, you know, it's like it's a kind of a gym feat when you're a kid just to see if you can and as an adult is just also living in a van obviously you can't do muscle-ups because there's nothing to muscle past. You're like hanging from a little bar inside the van but um >> but yeah, I started doing them again. I was like, "Oh, wow. It's so explosive."”
