I thought I'll bring up this thread rather than start a new one. As some ppl know I have patellar tendinitis and squatting/dead lifting is a bit of an issue. After reading a lot and seeing what others have done, I decided to do some glute activation exercises. Now I haven't squatted in a while because it's too painful on the knee. I was always adamant my glutes weren't firing and apparently if you don't use it properly, they have a tendency to stay asleep even whilst running and so on.
Basically I decided to do some glute activation exercises which included the glute bridge off the floor, fire hydrant, donkey kick back, 2 sets by 10 of each and I tell you what, it works wonders. After I did that, I went over to the rack and eased my way up to 60 kg squat with some knee pain but it was much more bearable than beforehand. So basically I want to keep continuing the glute activation exercises and try practicing the goblet squat along with some stretches just to get to the parallel mark comfortably.
i just thought I'll write that up in case others had similar problems and you may give this a go.
