He's not narrow at all, his structure is wide, he's just skinny now, in his day he was massive due to unusual genetics, crazy 24'' arms
lol dude, he's literally disappearing into that chair. His Size M athletic shirt is hanging loosely off his neck and shoulders, like he's a coat hanger. He looks about 0.7 Heaths wide.
"His structure is wide" -- did you even watch the video in OP?
He was wide, now he is beanpole. How does this happen?
