I've come to realize that compound movements for chest and back, no matter what training style, results in my arms severely lagged size and hypertrophy wise. Now why I think I've neglected to realize this is that I started training like powerlifters while really the results I wanted were hypertrophy and development. It's easy to fall into what you've seen especially with jail training illusion and get two different styles confused and on you go with the results your not happy with and no wonder why I loose interest because I'm not reaching my desires. Compound movements will sure help with strength, but for me that's it. I had much more development and size in my arms when I was 18 and natty before I fell to this illusion. I'm gonna purposely reduce chest and back for a few weeks to help correct this imbalance. It took me this long to wake back up and realize training like a powerlifter won't get bodybuilding results!
