Multi ply equipped lifters are JUST AS STRONG if not STRONGER than the best raw lifters xD
Looking to your squat videos, I reckon bring your stance in. Your knees will then be out in line with your toes as they should.
I have the same issue. Something that has helps me is to squat with a microband around your thighs, just above the knees. This helps activate the external rotators that are responsible for pushing the knees out.
So bring stance in, then work on flexibility so that I can pull off a wider stance?
I don't think I have weak external rotators, I just don't have the flexibility to do it. I'll work on the goblet squats as gooby says too
