Are there any specific video tutorials from a real reputable source on how to squat properly, not just the broad general stuff but the nuanced stuff too.
I'm not a fan of squatting coz of the damage to knees, but I also recognize that it has no rival when it comes to leg development
I am sure there are, but I don't watch those due to having people teach me in before and during my service. I had two knee surgeries so I feel you on that. I have to ice up and elevate after leg day due to swelling and all that. Some of the more studious guys in here will probably jump in and tell you.
