I've had various knee injuries and have tried strengthening my weak left glute, playing with stance, high bar, low bar and watched nearly every video on form. I tend to turn my left toe out more and have my left foot slightly forward when not concentrating but I'm so frustrated. I'm wondering if one leg is longer than the other or some other physiological imbalance because I' desperate to carry on squatting and remain injury free. Any tips on how to better my form or things to try so that I can continue on my path to getting stronger ? Apologies for bad video but train at home in a v small room ! Many thanks !
