In my squat, I find that I can get to depth, push up about an inch, and clear the squat another inch above that really easily. However, there's a point just above parallel where I struggle the most.
I filmed myself for the first time yesterday when I did 161 kg 1RM. I was constantly pushing above parallel for 3-4 seconds until I raised about 1-2 inches and could clear the remaining distance. There is an order of magnitude between the speed before and after that sticking point.
This is the weak point of my squat and I'm wondering if there is any accessory work I can do to strengthen that point or if there are any specific technique points I should be watching for. Tips and suggestions would be appreciated as well!
