Re: Batman physique thread.
They don't really explain or justify and actor's physique in the movie. Like they did not explain Superman's physique in MOS - they just showed him as a big bad sculpted dude. The offered no rationale behind why he looked this way or how he got his physique or why don't other Kryptonians have as good a physique. They just showed him and that's it.
So the same might be the case with Batman, they'll just show him as a big bad cut mother****er and that will be that, no explanation will be offered as to is his physique practical or not.
