Open up with the bodyweight exercises, then the heavies and then just work your way down.
I start with One Arm negatives, then pullups, then one arm lat pulldowns (One Arm negatives and these are for one arm chinup) then lat pulldowns, then seated rows, then barbell rows, then dumbbell rows.
A lot of similar exercises in there, but it works very well for me.
my back day is also my bicep day. but i like doing bent over rows, deadlifts, different types of seated rows, pullups etc. there's a lot of different stuff you can do, there's a bunch of different things i do and usually each workout is a little different.
Dude i do my back workouts same day as biceps....i dont have much experience but i can tel you now iv added enormous amounts of muscle thorugh bent over barbell rows, seated single arm dumbell rows, wide grip pull-ups (lats) and dumbell shrugs (traps) and weighted hyperextensions are great for lower back. remember to lift heavy and keep reps low (4-6). good luck!
