No offense guys but there's a lot of ignorance going on here about Bens physique.
First of, the constant comparisons to Cavill have to stop. Why?? Because they have two very different body types and the end result will appear different. People here act as though enough workout always equals perfection, it does NOT. Cavill has a certain body type that does not show much outside his regular clothes, that's why the confusion was massive during his comic con appearance back in the day. We all know how that turned out.
Ben is a more powerful looking guy, with his size actually showing outside of his clothes. That's a big chest with naturally wide shoulders, a perfect look for Batman. HOWEVER, the area in which Cavill has a massive advantage is the slim waist, in which Ben is the complete opposite and has a wide waist not really allowing his upper body to appear as broad or as V shaped as Cavill is.
Trust me guys, Ben is going to look every bit as good as Cavill, just in his own way. A lot of people made the mistake of Calling Cavill small before the shirtless pictures, let's not make that mistake with Ben. Wait and see is all I'm saying, give the man the benefit of the doubt because fanboys tend to overact something fiercely certain times and are usually dead wrong, as the case with Cavill proved.
