First off im 5`10, 210lbs at 12-14% BF (100% natty). Im a tri&delt pusher meaning genetically big shoulders and arms, smaller chest and I also genetically have big strong legs. For over a year I was doing:
Legs&Biceps (big legs, i dont need a lot for em to grow)
Although even though I have genetically good arms they are only 17 inches atm. And I feel they need to be about 18 inches to be more proportionate to the rest of me. Could anyone give me advice on maybe switching my split or something that would help me get them to 18 Inches.
