I mean he's in his 40s now, ain't no way he can maintain his Immortals era body. Plus he always had a thicker build than someone like Hemsworth. Wasn't he a chubby kid? He pretty much admitted that he only had visible abs when he was completely dehydrated.
Yeah, if he doesn't get anymore big projects that he needs to workout a lot, like Superman or Witcher, I can see him getting big like Russell Crowe, lol. Unless he gets the James Bond role, which probably unlikely now since he is on another Spy movie already, Argylle. I think doing that movie is a bad move, if he really wanted the James Bond role, unless that becomes a new big IP. The odds of that getting as big as James Bond is very slim though. Warhammer, if that's even gonna happen, feels like it is gonna be a ton of cgi, so he doesn't probably needs to be fit in there too.
