I am tempted to throw up a "newbie alert" a la Jennifer, but my choice of topic (which might be incendiary...) and obvious lack of elan ought to show up quickly here and out me!

I am really interested in developing big, healthy muscles. I want to be healthy and fit and strong. I'm not worried about getting bigger, but I do not want to end up a competitive bodybuilder. That's just not the right path for me. I'd like to have well defined, muscular arms that are not huge.
In looking through the abcbodybuilding site that Mrs. Jim mentioned in her sticky, I found the exercises titled with things like "Freaky Big Legs" and "Mammoth Necks"...which led me to wonder if specific exercises lend themselves to increasing the size of muscles (I know L2L gave this a name in one of her posts, but I'm forgetting the word), while others tend to increase strength rather than size? In going through the dozens of possible exercises for each area of my body, what are the best guidelines to follow for selection?
Are some exercises geared towards competitive bodybuilders, or do bodybuilders just lift more and harder?
I would love to learn more! Thanks in advance...

... It's my pet peeve!!!!!!!
Got to say, they’re really great — they’ll accept anyone, male or female, who’s serious about lifting (there's a real camraderie among lifters who know what they're doing and aren't in the gym to show off with riduculous weights and bad form). And I’ve learned SO much from them just talking about what they’re doing.
