That's right techniques that actually work to getting your squat more comfortable and mobile, also no nonsense or an overload of information that makes the mind boggle to what you are supposed to do, just apply and feel the difference in your squat mobility.
If you are following Ido's squat 30/30 on Facebook, 30 minutes for 30 days like I am, I have come across those struggling with compromised form. Now I do my whole Be Activated sequence most days ( there is more than what I have shared on the video and the articles.) then before doing the 30/30 I was doing the toe prep from the fundamentals of human movement course I went on and since adding in Ido's 2 routines below thing are all coming together and progressing quite nicely. So I suggest that you follow these video's and see how your squat and body improves with your practice.
My toe prep below is learned from Tony Riddle, who's videos are below mine showing the other work on the poles (broom handles) The work helps your feet become more functional, which in turn aids the squatting posture as you gain a better base throughout your feet.
Just my musings.....
