I started neglecting my arms almost a year ago since I was only concentrating on compound lifts such as squats, deads, and incorporated cleans for a short while. As a result of that and injuries that laid me out of the gym for awhile, my arms are puny and have no definition whatsoever. It seems like my legs grow the quickest, which I don't mind at all since decently sized legs look great, but I would really like my arms to catch back up to how they used to be.
With that said, I'm going to hit them twice a week. My training regimen is pretty unorthodox in the sense that I don't really follow a set routine. I just go in there and make sure to hit one compound lift (either bench, front squats, or deads) and then other random stuff such as pullups, lat pulldown, rows, incline, etc. So would doing shoulder presses, dips/close-grip bench, and random curls 2-3 times a week be okay, assuming I keep it at 5-6 sets each time?
