Back muscle exercises?

[nukem2k5]

What sorts of things can I do to work out the muscles in my back?

My workout is kind of messed up right now: I do arms, chest, shoulders on one day.  Next I'm supposed to do my back and stomach.  Then the last day I do legs.

I'm just stuck because I don't know exactly how to work out my back very well.
