Here's this morning's squats at 140kg. Focussed hard on early knees all through warmup, does it look any better? (I think these are shallow still).
Main reason for posting is to report some numbness in my left thumb the past few weeks, appears as I do my worksets and persists for a few hours. I've searched the forum and been working on keeping a shelf on the upper back for the bar to rest on, still had some today, any other cues I can try?
