Sigh, I knew that I should have edited out the tap dancing from my vid as it was sure to get pointed out
. 00Snitch, you are absolutely right that I spend too much time trying to find the right foot position, and it could very well be that that is how I hurt my leg. Tapdancing also tires you out before the workset. I know what Soulman is referring to when he says that the bar feels lighter when lifted in the right way, so I will strive to make that my standard. Right now it looks like these are my problems: lacking hip drive (especially on the way up), hunched back, not getting low enough, and presquat ritual. That is lots to work on, but I think that my knee positioning has improved from last time, i.e. no longer letting them go forward the whole time, but still managing to kick them out (horizontally).
Thank you all for your feedback!
