I am training to prioritize and add more mass to arms, delts, traps and calves. I am curious to know if anyone has any thoughts on how to train chest, back and legs so that I maintain the current size or improve quality but still have enough energy and recovery for adding some mass to the bodyparts I want to improve. I am 5'10 235-240 at 8% right now, been training for 15 years and would like to stay around there but still improve arms, delts, traps and calves.
