Bar placement is too high, bring it lower so it sits just below the bone that is the spine of the scapula. Will need some getting used to specially with shoulder flexibility if you are lacking there.
Also need to stay tighter specially in the hole you have the strength to push more but losing tightness at the bottom. Take a big breath into your stomach and hold it tight - do not breathe anymore in or out until you start the ascend - i would even recommend not to breath in or out until you are back up for the beginning.
Work on some weighted ab work and strengthen lower back.
As for the right knee - start foam rolling the ITB before squatting, rolling the piriforming with golf ball/tennis ball, stretching the glutes. I bet that’ll fix it.
I’m not an expert however i compete in PL and i have squatted 222.5kg raw at bodyweight of under 83kg in the IPF. I have represented my country at the World Championships and I own a hardcore strength and conditioning facility where i train many other athletes who also must do squats and get good at it. So that’s my 2 cents for you to start with. There are more things to fix down the track but fixing those will help.[/quote]
you will do for an expert for me…
good to see you on the board, hope all is going well for the Oct comp you are managing
