I bet if you two stood next to each other he would be the bigger guy.
Plus he has better shoulders, chest and bis than you. You have a better back and legs.
he has far better structure than Simon.
he's a natural mesomorph. a naturally large,muscular guy. Simons an ecto, you can tell because no matter what he weighs he always has that stringy, blown up middleweight look to him.
Simon has crafted a very good build, given the genetic hand he was dealt, but a guy like flint would destroy him if he put in the same effort
granted that's a big "if" Simon has done it
