I'm driving my hips back instead of up on some reps. I also have a habit of looking up when trying to drive out of the bottom so I know I need to work on this.
Last week I noticed my knees were collapsing in a lot. This still needs improvement, but its not nearly as bad.
My knees very clearly sliding forward on the last two reps of video 3. I was exhausted on the last set (bad night sleep) but I was aware of it happening. I don't think it happened other than those two reps, at least not to that extent.
Bar Position - Last week I had some shoulder pain due to the bar being too low. I could feel the bar slipping down my back during each rep. I watched the bar position video, and changed the bar position accordingly. My shoulders felt much better, but I'm not entirely sure I had the position correct.
Low back fatigue - After doing a set my lower back is exhausted. Not in pain, just tired. 15 Minutes after the last set it feels fine again. Is this something I should be worried about? Does it look like I'm doing anything horribly wrong that would cause this? Or is this just caused by my back being extremely weak?
These look good, looks like you've got the concept down. You seem to correct yourself pretty well from rep to rep for the most part.
Just fight to keep your chest up as you come out of the hole, bar over midfoot, and hips straight up as you noticed.
As to your questions, your bar position looks fine in these. And low back fatigue is going to happen, but yours could be from the slight tendency to fall forward when fatigued. This is common and you just need to get stronger, IMO.
EDIT: Oh and you could tighten things up if you keep your knees anchored after that first 1/3rd-1/2 of the way down. Don't let them shift around.
