I've been trying to do barbell squats over the past 2 months, changing my form trying to get it as proper as possible. Im currently cutting, so im only doing around 5x5, 4x6, or 3x8 with some good weight. Thing is, today while doing squats I felt a horrible pain in my knee caps while coming up... And even once I was done doing the set, I could still feel it... So i decided to stop doing squats... Im thinkin of maybe using squat machines or something... Any advice? I know nothing could quite substitute the benefits of a good well done squat, but its been very difficult for me to get it right and feel it right, without having pain. Also, im not sure if the pain in the knee cap had to do with the HIIT i had done last week, but even if it does, it still shouldnt hurt THAT much... Advices?
