Just to start off, I am on a 5x5 bulking workout. I am eating plenty of calories and making a good gain (about a pound a week). Started off at 159 and I have worked my way to 171 pounds at 6'1. I have very long legs and very long arms (74 inch reach). My torso is pretty short (which causes an odd look I think) so I am wondering if I might need to workout my arms more (with the 5x5 program) with curls or something in order to get them bigger or should I just wait and see how progression looks when I weigh in at around 190-200 with just the standard 5x5? I feel like that would make my stomach seem flatter and make me look generally bigger since I have longer limbs.
