No disrespect to Noema, obviously, but I'd still like a second opinion on that. Am I doing it that wrong? It is very possible, but I thought I'd read SS carefully.
Stop my video around 15-16 seconds in: my bar placement and elbow positioning seem, to me, very close to that depicted in the picture on the right of Figure 2-1 in SS, 3rd edition. It is true, though, that at Figure 2-23, his elbows are raised more than I do it, but the placement of the bar seems very close, as is the back angle and the general body positioning in the hole.
Anyone wants in?
No, you are not doing it that wrong. It's very close to the position you want, but it's still high enough that it's affecting the mechanics of the movement so you have to work extra hard in the middle to bring the bar back to its vertical path when going up. The arrows show how the bar is resting on the spine of the scapulae:
That's where the bar should be. That's the position of your arms to hold it in place. As you can see, it's really just an inch, maybe less. Since you seem to have a longish torso, the lower you can keep it, the more you'll be able to lean forward to open the angle of the hips relative to the knees at the bottom without deviating from a vertical bar path over the middle of your foot.
Here's how the squat looks like on the way up, just as you reach your sticking point. Notice how the bar has traveled forward increasing the moment arm making you work extra hard to keep the bar balanced. This is clearly the hardest part of your squat, since not only are you fighting gravity but also against the moment force produced by the distance between the bar at that point and the ideal vertical path over the middle of the foot.
I believe you are placing the bar right on top of the spine of the scapula, (orange) when it should be under it. Red represents a high bar position with the bar on top of the traps:
Now remember: I'm not an expert
My opinion is just an opinion, so I could be wrong of course, and if you feel comfortable squatting that way, that's fine! But in that case just try to keep the back a tiny bit more vertical so that the bar path doesn't deviate as much on the way up.
