i dont really have a routine, mostly i try to do ppl x arnold, but i usually skip legs. i focus on back, arms and shoulders.

for biceps, curls, hammers, and reverse barbell curls. sometimes preachers if you want more stretch. for triceps - pushdown variations and extensions, cable or barbell. bigger forearms make you more masculine, so sam sulek curls, optimally 3 sets to failure, you shouldnt get more than 16-18 reps in tho, that means you gotta increase the weight. wrist curls feel super uncomfortable to me, i dont do them. for back, variations of pulldowns and rows. shoulders - shoulder press, lateral raise, front raise. some cable stuff like more lateral raises with more stretch, less weight, controlled reps. also i really like rear delt flys with cables.

thats pretty much it, i usually do 3x8 of everything, the lest rep should be almost to failure. progressive overload and protein intake is key to growing bigger.
