be careful on the arnold forms though. he may have been MASSIVE, and was lifting far more than what normally people are lifting these days, but if you look at some of his old pictures, you'd see the weirdest forms ever. when lifting on his biceps using a barbell, he would arch his back completely, for example. however, reading up on it, you'd see reviewers saying that 'if you lifted that much, then you were forgiven'. so you may take arnolds workouts as a guide, but dont take his form.
