front military, rears, and DB presses were always a staple in my delt routine for probably 20 years, then I had too much pain that wouldnt go away, even with cortisone injects and therapy. I then read an article somewhere called "Stop the presses!" that explained it all in detail, like the OPs therapist said, are not a natural movement.
Now all I do is side, rear and froant laterlas, just an extra set or two of each. Same total sets as before, just no presses. My delts haven't lost a bit of size or shape, in fact still improving since I stopped presses. And I'm 46
But I have a bud thats world class in natural RAW bench, uses all the Westside routines, and heavy military presses are always included, and he has no problems.
