So, I feel quite comfortable on the PE. A bit of just shaking and steadiness. This video is from my second week at 5x60" and this video is my fifth set. Clearly, I can still refine the pose, but as per meeting mastery, I feel like it's there. The iM, however, is not. I'm currently using fractional plates (because I see no other way of ever possibly conquering shoulder extension). In this form check, I believe I'm using about 1.25 lbs. My question is that my shoulders/arms in one case don't seem high enough, the other is that I want to roll my shoulders back, but they don't seem willing/able to do that. When I bring my arms up to the iM position -- 90 degrees -- my shoulders just naturally want to elevate a little bit, and my head wants to protrude forward. I know to externally rotate my arms, to keep them shoulder width apart, and to keep them at shoulder height, and the blades retracted (which I am actively doing in every instance). But I'm not sure how else to remedy this. I warm up with table rocks. I'm currently on FL/PE2, so I do tables for a few sets on other workout days a few times per week. I've read @Alessandro Mainente mentions that the arms HAVE to be shoulder width distance. Of course, I could be splitting hairs and my arms are high enough, and my form is good enough, and it's just that the weight isn't there, but something tells me that isn't it. Here are the vids:
