Hey guys. So I did F1 today and the hinge row felt kind of strange to me. I watched the video on how to perform it a few times, and I felt like I had trouble getting the form down. I believe it's where you're supposed to simultaneously hinge at the hips and pull shoulders back. The movement to me looked like you're supposed to pull through the rings, so I tried to envision that. It felt as though I had too much bicep involvement, also my right shoulder had slight pain when doing this as if it was trying to externally rotate when I began pulling through. Any tips?
P.S. I had a question about the integrated mobility portion of the hinge row. If I have rounded shoulders/kyphosis, should I be doing the upright lat lean? I feel that when I do this it's pulling my shoulder forward and I feel pain around my pec minor/clavicle area pretty bad when I do this. Any tips?
