Rear delts on back day?

[Venum]

whats up all..I have been working my rear delts on back day for the last couple of weeks...seems to fit well into the workout, but I am a little confused on how many sets to do after back.....I have been doing 4 sets of standing cable column reverse flys (taking off the attachments and just holding the bare cable), and about 3 sets reverse pec deck machine...is this enough? too much? thanks for any help!

I never set a limit on how many sets. Listen to your body. It's a pretty small muscle head so it shouldn't take a lot. After a typical back workout, my rear delts are usually sore the next day.
