I don't train front or rear dealts directly. I find that when I work back, chest, and shoulders those two little guys get plenty of work.
A good replacement for face pulls is bent over rows to the chest. If you stand up slightly taller compared to a full bent over row then you'll hit the rear delts and upper back really well. That one is also good for full trap development, instead of wasting time on shrugs that only hit the upper traps.
