Proportional to weight, though.
his weight is pretty much 185-190 Imo. I actually don't know, but either way his dads friends (grown 40 year old men) dared him to do 10 pull ups because they cant and he did 30. he did them really fast too.
But he pulled himself up from basketball ring court thing about 10 times while his friends couldnt do 5..
He's very very very fit but eats like a btich.
