I,Bodybuilder Arm Specialization?

Coach Thibadeau,

I am about to embark on the I BODYBUILDER and perfect rep method/routine. I know which bodypart(s) need the help, esp. my back. When I dieted down my back was the most lagging with the arms a close 2nd. I see a specilaiztion for all bodyparts but arms. If that is a problem does the back specialization help the biceps and the chest/shoulders help the triceps or do you make an arm specilaiztion just for that?

Thanks in advance
