Unkown please tell me what Dr. Stuart McGill is teaching that is incorrect or wrong. I would like to read it, and post it right here. I can say the same thing about functional patterns. Naudi aguilar in his “how to correct knee imbalance” video was teaching  myofascial release incorrectly as he was demonstrating quick movements of the quadriceps over a medicine ball. Quick movements should be avoided when performing SMR.
