You might have a different opinion of what makes up ideal. For my purposes, however, there's nothing better than being able to flip a car nonchalantly, and then rip off your shirt and display your abdominal vascularity to the delight (or horror) of random passers-by.
Certainly, based on your goals, you're going to have different opinions of what's ideal. If you're a bodybuilder who's all show and no go, you might like the looks of a wasp-waisted Frank Zane. The man certainly was ripped, but he also did a hell of a lot of yoga, which is how his penis turned into a overly-large clitoris. Tragic story, really.
Maybe you're more into the power-bodybuilder look- guys like Jimmy "The Iron Bull" Pellechia, or Branch Warren, the guy from the Animal Pak ads, or Johnnie Jackson. Definitely a cool look, and nice to see that those guys can actually move some weight. Not my deal, however- I get bored doing lots of reps, and I'd rather do shots of bleach than sets of cable crossovers. Nevertheless, respect goes out to those guys, in my eyes, and I try to incorporate a bit of their training into my style.
Since much of my inspiration comes from comic books, however, and I'm practically a midget, I'm gonna have to go fantastical on your asses and say MY personal ideal is:
Not the pussy Hugh Jackman Wolverine, either, but straight up, 5'3", 220 lbs, all traps and forearms Wolvie.
Train how you want to look. Just try not to look like Hugh Jackman.
