yin yang principle

Hi everyone, I just finished a growth-surge phase. I had impressive/decent results - reduced bodyfat by 3% and gained 7 lbs of muscle. I followed the suggstions of the growth-surge phase III where yin-yang principle is used. For instance, I would do 1 set of chest followed by 1 set of back, and continue for about 3 sets of chest and back. My question is, how effective is this training program now that I am done with the growth-surge phase? My goal is to further gain strength and size. I find that training according to the yin yang principle keeps me fresh and I don’t get fatigued very quickly.
My stats - 175 lbs, 5’11 inches, 175 lbs. Also, any advice on diet would be greatly appreciated.
