I remember reading on the internet that this guy wasn't believable for the role due to him not being buff enough...
A lot of people aren't realistic about what is buff and what isn't, their sense of reality is mostly wrought by media/movies, but they don't have a clue of what is believable or not. And a lot of people won't have this shape in their whole life, due to bad life hygiene a lot of the time. People love to talk about stuff they don't master...
Anyway, great shape in order to play a military guy, not too buff !
