if you're new or don't know what you're doing, buy arnold's encyclopedia of bodybuilding.
it gives you good basic information, and pictures and descriptions of the proper way to do pretty much every type of lift out there.
You can follow the routines if you want, but you've gotta take some of them with a grain of salt, since arnold is obviously abnormally more responsive to training, and used to take steroids.
But if you follow is beginner's routine (which is pretty much what he recommends for the first like 3 years of lifting), and just do the sets/reps to your own max, you'll get pretty strong.
