Workout bros - is it bad to target arms & shoulders in back-to-back days?

Yes

I hit back and bis the same day to maximize healing time on biceps.

eta not bad actually. Just not optimal.

Depends on your genetics

I do a 5 day split.
Back,shoulders,legs,chest,arms.
Usually do 12-14 sets for small muscles
15-18 for big muscles
You should be good though. As long as your muscle is a secondary muscle one day in an exercise and a primary muscle another day in your exercise.

However if you feel like its too much you could switch the weighted dips for weighted dips using a bench instead. Due to the placement of your hands it will almost exclusively target your tris.

Answers are all over. I used to workout bis on back day and tris on chest day. I started working them out on different days and both arm muscles grew bigger.

The key is to letting any muscle group healing at least 48 hours. So I workout 4 times a week and chest day is never within > 48 than my triceps day and same with back/biceps.

frick me thought your OP said arms and back in back to back days.

I would give it at least 48 hours between working biceps and working shoulders.

You can work different parts of your shoulders on different days no problem.

I do a 3 on 1 off route with Chest/tris, Back/Bis, Legs/Shoulders, off to give ample rest.

I do:

Mon: Legs
Tue: Chest
Wed: Back
Thur: REST
Fri: Shoulders
Sat: Arms
Sun: REST

I try and get the big body parts out the way first, and hit the more specific ones later in the week. That being said, there is no rest between Shoulder day and Arm day.

I don't know if it's right or wrong, but I haven't hit a problem with it.

Let me blow your minds real quick:

6 day week:
Legs
Chest/Back
Shoulders/Traps
Arms
Legs
Chest Back

Terrible idea. Here is my routine. And needless to say, it reels in the ladies.

Mon: Forearms
Tues: Thighs
Wed: Neck
Thurs: Rest
Fri: Quadriceps
Sat:Rest
Sun: Calves

Well...its certainly January.
