Back or biceps first

[die faster]

i always do back first. for all the reasons everyone wrote here. but sometimes just for a change up ill do it backwards for a couple days. fore-arms, bis, rear delts, back. when eating alot of carbs, this gave me some of the craziest forearm/ bicep pumps ive ever had. but while cutting, i just felt them getting destroyed and over trained.

If you kill your back workouts and have plenty of compound movements, you won't have lagging biceps to worry about.

My lats were so wide I could fly and my back was thick as fuck, but my arms were lagging until I started doing arms on their own...now my arms are scary

Yeh...some, such as yourself, will have to take that route to really get development. Everyone is different, and everybody has an area that needs special help to bring up to par with everything else.

Sometimes doing direct and dedicated work on a lagging muscle group is the only way to get that growth
