I go to the gym and do weights because I like the way exercise feels, the high you get when pumped up etc. Getting muscular is a side effect of that

. Don't do it to impress girls though cos then it's not worth the effort.
I agree that photo 1 is the way. But the type of guy on photo no. 2 doesn't give a shit about what women think about his muscularity, therefore I'm sure he has no trouble getting woman. And I respect guys like those because it takes a shitload of effort to look like this.
And to guys telling that "oh this is way too much you don't have to look like this bla bla..." Don't worry, you won't look like this ever.
Just look what you think you should look like and what makes you happy. I think that's more important than to impress anyone
