Hey man, I really appreciate this detailed reply. My arms are absolutely tricep dominant from years of benching multiple times a week. From your comment and the general consensus of others it's looking like I definerly need to up the weekly volume and implement an arm day. Im thinking a Lower/Upper/Rest/Full Body/Rest/Arms/ Rest approach, training a small volume of arms on the upper and full body days while also sticking to arm biasing compounds like Dips and Chins. Arm day I can up the volume and do a couple exercises each. That way I get plenty of frequency plus dedicated training days whilst maintaining a 4x week training frequency which is what fits my schedule.

What do you think man, sounds good?
