^ yep, I'm definitely a posterior chain squatter by habit. My collapse is the same as you describe - it only happens when going heavy as I come back up (gets me through the sticking point then they go back out). Core brace is something I'm pretty good at, and the knees come in whether I low bar, high bar or front squat (but only at the heavier weights I can handle or when I fatigued). Just doing high bar at the minute due to a sore wrist (the massage side of things has been picking up and I think I've used my right hand in the wrong position)
Yesterday - training at a friend's with no reception hence the late catchup
high bar squats
145x1 x 4 sets
145x4 - rep pb (happy considering the fatigue from the previous days). Tried smelling salts for the first time - got a bit close and thought I'd never get the sense of smell back in my left nostril, lol. They helped though.
pause squats (2RIR)
115x4 x 4 sets - comfortable enough, but my mate/coach pointed out I probably shoudn't be pausing at the bottom as my sticking point (and knee cave point) is around parallel not at the bottom. Will be playing about with this tomorrow.
65x2 x 4 sets - was a grind, but I don't like pressing in the oly shoes, thats my excuse
170x3 - accident, should have been 160
160x3 x 3 sets - easy enough, going to try wearing the belt on just 2 lever holes, not locked in to all 4 (lever belt) to see if this helps, if not I'll stick to beltless.
paused incline bench
60x10 x 4 sets
25x12 x 2 sets
started feeling a cold coming on yesterday morning and felt it more this morning so didn't do much in the way of cardio type stuff
row 1k @ 2:01 pace
calf raises on smythe
80 x 4 sets
posture nod things / scap dips x 3 sets
I never use my indicators, I don't like people knowing what I'm up to
