I'm asking this b/c while doing front shoulder raises I tried something. Normally I raise my arm forward and when I get to the top my palm faces down, and I normally keep that position.
This time I tried rotating my palm inward (facing towards body, like a Hammer Curl), and using that position, and noticed a big difference. It seems going palm face-down works part of the side delt as well as the front, but I don't feel the side delt near as much with inward.
I'm used to seeing people go with palm down and that's how I've been doing it, but now I'm wondering if I should have been going palm-inward all along for effective isolation (since I do side raises as well).
Any thoughts?
