What's a good weight lifting routine (best answer chosen)?

I'm going to get a membership to the YMCA and I want to know the best routine that would work for me. I'm 16, 5'9, and pretty skinny (120lbs) so I don't have to worry about losing fat, I just want to gain muscle. I was thinking of weight lifting every other day and running a few miles the days I don't weight lift but i don't know which exercises to do.
