u see, you approach is typical "more-is-better"...a classic mistake most bbers make...
maybe doing less on your stronger side to even out? ever thought of that?
I know it might sound contraversial, but sometimes you gotta do less for better bodypart to bring up the weaker one.
I'll explain:
when you do less for stronger part you:
1. maintain the stronger part size/shape/etc but temporarily "freeze" its further growth
2. at the same time you have more enegrgy to work your weaker part and develope it further to bring on par w/ weaker part.
3. able to mentally concentrate more on your weaker part.
So in essence, you will be doing maintenance work for your weaker/smaller part while cathcing up growth of your weaker part.
Personally, I had my massive chest, back, and shoulders overpowering my arms. I actually STOPPED any exercise for chest and back for ONE MONTH and only focused on arms. At the end of it my arms impoved significantly and my chest/back have marginally diminished, thus creating overall balance.
