Bunjamon saidI think it's crazy how athlete's bodies have changed over the last 70 years. These guys would probably get laughed right out of the Olympics today. Most basketball players, track and field athletes, swimmers, and boxers' biceps these days are bigger than these guys' calves. I guess a lot of this can be credited to the shift away from amateurism and allowing professional athletes to participate, but a lot of amateur athletes on this site look like they'd put these guys to shame...
Something to think about!
I think what's more interesting is - while many professional athletes do have these bigger, better bodies - there are still plenty that look almost average to the outside observer. They are some of the most physically fit people in the world, and yet since they dedicate their training to performance rather than aesthetic, there's no real visual manifestation to their fitness. We might just view them as just another moderately in-shape person...until we saw them perform.
Just another reminder that looking physically fit and being physically fit are two very different things.
Edit: Not to say that achieving the look of physical fitness does not require significant work in itself, because it most certainly does.
