yes also good. Although people donīt like to talk about "isolation" i think there are exercises which give a unique training effect and this is one of them... in my Humble opinion 
Yeah, the whole "isolation" argument is a tired one.
If you want to say you can't isolate and work just ONE part of a muscle, I'm okay with that. But, you can certainly
emphasize certain parts over another.
Would these same people rely on front raises to help rear delt development?
Would they dismiss front/rear raises all together because they are "isolation" movements, claiming all you need are presses?
So, when their rear delts lag behind and need to be brought up, do they just do more pressing - since that's all they "need?"
Yes, let's just do more of the same shit that hasn't been working in hopes that it
will work.
