I just picture Bruce as this powerhouse of a man. Officially he weighs 210 but in my head he could be as much as 225. At the bare minimum Batman needs to be a heavyweight. Get that Christian Bale shit out my face.
Bale was probably the biggest Batman in Batman Begins, what are talking about?
The size Affleck had while in the costume is Batman to me. Bale had a very 'form fitting' costume.
That's just muscle padding in his costume and cgi abs.
This is what Bruce Wayne should look like. (He put on so muscle Nolan had to tell him to stop)
