i dont see nothing fishy. Since i see some strong skinny guy and big muscular weak guy.
Sometime I think the strong is not 100%= musclemass.
But Kyomu, it's a 14 year old kid apparently benching 435lb. That's a FOURTEEN YEAR OLD KID BENCHING FOUR HUNDRED AND THIRTY FIVE POUNDS

Bearing in mind he threw it up reasonably easily, his actual max bench is higher than 435. Also, if he had arms that were a 6 inches long, a huge chest and triceps and was wearing a shirt I'd maybe give him the benefit of the doubt. But he doesn't and he's lifting raw. lol
