Thats why shoulders and arms are at the end of the week for me.
I don't spend much time on the front delt because it gets plenty from chest day. Middle and rear delt on the other hand it worked pretty extensively. Every so often I will do some over head press or plate raises but my front delts have never been small. Bi and tris sometimes get their own day or I'll stack them with chest or back. Depends on my mood and how much time I have.
