Quad muscles.....

I've been thinking a lot about quad muscles lately for obvious reasons. I've always wanted defined legs. I wonder if it's humanly possible to get quads like these (with no 'inject-able' assistance). Don't get me wrong, I don't want crazy muscles.... just defined ones.

I suppose this guy can say "it hurts right here" to his massage therapist and there would be no guessing which muscle was affected. Gulp!


Gotta bulk up! :)
