Great article. I would add:

-the first part of a squat is a shifting backwards of the hips
-keep your weight in your heels and outsides of your feet
-hold abdominals tight to keep the chest lifted

I work with so many clients in regaining their ability to squat but not necessarily all clients can squat to the floor. That’s ok. We will work around any limitations.
