best advice i can give ya is what i said....dunno why one is larger but is lagging. maybe ya injured it or something? when i was younger, i helped my father move a couch (he wasnt much help), and i supported the weight of the couch with one arm, and guided it with the other. to make a long story short, my bi's now have similar shape to that of arnolds (no where near size, but one of the peaks on one is great, while the other is more rounded). it was also injured for a while after that, and i noticed that the weight i was accustomed with, was much less then the other. my cousin (who is my workout partner) suggested the same routine i gave you, and they evened out in the end (weight and size wise, although i still do not quiet achieved the peak....even after all these years). keep the reps the same for both arms. the smaller, stronger arm might be able to do more weight/reps, but in order to keep yourself symmetrical, you are going to just have to deal with it for a while i guess.....keep me posted on how this works for you (PM or email), maybe i can help ya more if you still havent seen a change.
