I mean, the guy is a powerlifter who doesn't really care about aesthetics but just about lifting as much as possible so he eats a lot and lifts heavy. So it's understandable that he can do many pull-ups because he's strong. His bodyfat is probably like 23% but he's very muscular so looks way better than the average, sedentary fat. This is the type of body I'm talking about. High bf% but strong https://qph.fs.quoracdn.net/main-qimg-ba62481d229e4d987eaaa3ec7bd9367e-c That's not him btw, just the body's type.
