Things have changed with guys and physiques over the last several decades. It seems like just about every pop singer and actor is ripped. Going back years and looking at the macho celebrities--John Wayne, Paul Newman, Clint Eastwood, George C. Scott, Kirk Douglas, etc---none of them were what you'd even remotely call ripped. Muscular, maybe, but no six-pack abs or sculpted biceps.
I can't remember a movie in which Humphrey Bogart had his shirt off. I can't remember a movie in which Mark Wahlberg doesn't have his shirt off at least once.
