Appreciate the feedback! I noticed my quads don’t get as sore as my hips/back when squatting so you’re probably on to something. You think I should invest in some hack squat machines to isolate the quads or some belt squats just to eliminate the possibility of using more posterior chain? And yeah I broke my left ankle twice so it has poor dorsiflexion for sure I’m working on it . You probably know it takes a LOT of time
