I need to grow my calves and thighs. lol. I'm a lot stronger than my stick legs. I can move a lot more weight but my form wont get better until I actually add mass to my legs. Taking weight off to 'fix technique' will just make me weaker and waste time and solve nothing because until I grow mass it won't be solved and lighter weights wont do that. Just clarifying my thoughts in my diary no offense intended. I'm better served by continuing to progress and keep working on fixing weaknesses AND adding leg mass.
Btw the above is why Mutombo call pull 220kg like its nothing having the leg and back strength to lift it and yet he struggles to squat more modest weights. The reason is not his lack of strength, it's a lack of mass in the legs. He has thin legs which prevent him from being a good squatter - they are plenty strong though as shown by his pulls. Squat proficiency is determined by leg mass and vice versa.
What? The reason Mutombo can't squat more is certainly lack of strength! If could could squat more he would be stronger. Fix your weaknesses but you are really getting off track watching elite athletes and deciding what the "secret key" is to their success. Also, no offense but your conclusion comes off as self-serving ( eg. I'm actually really strong but because my legs are thin I can't move the weight; these elite guys aren't necessarily that much stronger than me but have bigger legs ). If this was the case then this hidden strength of yours would manifest itself in all the avenues that aren't specific to supporting weight in the squat.... So you would be able to run really fast; jump really high; shot toss huge weights; jerk big weights (mostly leg drive - not arms ), etc. I'm not trying to down you but it's really dangerous to analyze a bunch of really elite guys, notice a pattern and then let your confirmation bias convince yourself this X is the key! If squatting is all about leg mass rather than strength.... it's not really a very functional activity now is it? So unless you are a PL... why are you doing it?
Anyway, for years people watched elite sprinters and were certain you had to be tall with high knee action. Then Michael Johnson came along and everyone changed what is ideal. Now Usain Bolt rules the day and everyone talks about how great it is to be tall. The fact is there is more than 1 way to skin a cat. In fact there are a million ways to skin a cat! You choose the path that's easiest for your body and gets YOU to improve the most. But keep in mind that thats not the only way and you could always do it a different way. I honestly have never seen you get stuck; just impatient. Stuck is when you don't improve for a LONG time. There will be months where you don't add weight to the bar. You are not a beginner anymore. Keep training; keep your form good and when you get TRULY stuck; don't be afraid to reevaluate your training... Just to add a small reminder:
That guy is 5'8 170lbs. He is known in olympic lifting circles for his scrawny legs and overall scrawny frame. I don't know how much he squats but he can clean 450 and snatch 380 so I'm sure he his squats pretty damn good, skinny legs and all. More than one way to skin a cat; no excuses do it your way.
