Yes, they seem more humanoid than the rest, to be sure. And a small waist goes a long way. No amount of muscle can compensate for a fat gut.
But if drugs were taken out of bodybuilding (hypothetically, of course, since it will never happen), then it would really come down to genetics, proper training and diet, and discipline. Not that there is none of it presently; just that drugs gives such a wide margin of error that people can get away with improper training and diet and still make a good showing if they get their chemistry right and maybe "better" than the next guy. So there is not much to learn from them or to aspire to, unless someone is willing to go down that bumpy and treacherous road.
It really ought to be about health, fitness and all the other good stuff we associate with exercise, good diet, and clean living.
Yeah, I'm bored. Not much going on right now.
