Like the other guys said, and like you are doing, work your upper back as often as possible. Make sure you get some kind row/chins/shrug movement every week to hit all the angles. Change up the actual exercises as often as you need to stay fresh/motivated.
Do as much back work as possible standing on your feet.
And just in a general way do more sets (6-8) and fewer reps (6-8) than the "traditional" 3x10 setup.
