My little teen cousins "boyfriend" can do 65+ lol. He prob weighs about what I did when I was his age too. Lots of young kids can do crazy amounts.
There's people who can do like 100+. Youtube it. Idolized above can do 40 wide grip pullups, he says probably same number of chin-ups, but chin ups are like half as hard, I bet he could do over 70 if he pushed and he weighs wayyy more than I did.
It's way easier than you seem to think it is if you're skinny and have lean muscle.
You can't do 70 pullups in one set.
