Hi all, whenever I reach just above parallel in my squat, my hamstring (biceps femoris tendon) “snaps” over my fibular head on the outside of my knee. It makes a loud clunking sound every time and you can visibly see it snapping. This even happens with just passive range of motion too when I bend my knee past 90 degrees. I’ve had this for years and haven’t been able to get rid of it. I’ve tried stretching my hamstrings but that doesn’t seem to help much. Are there any mobilizations or exercises to get rid of this so I can squat deeper without it snapping?
