I seem to be doing something wrong when I squat. I’m using very light weights (30 lbs) and really focusing on form. I always go just below parallel making sure my knees don’t turn in. I’ve watched dozens of videos on squatting. But without fail, I’m in pain afterwards, much more so than any other exercise (it usually hurts a bit right away and is worse the next day). This doesn’t occur with split squats. Any advice? I guess my next step is to see a personal trainer?
