The video talk about the squat position and mobility in the squat. When squat is mentioned we usually associate that with strength training, the barbell squat or variation thereof, but the squat should instead be thought of as a primal movement and our default resting position. Squatting is very good for our body, it add to our muscle and strength but also mobility and longevity. It help improve balance and posture and it really good for our joint health. Look at a baby or young kid, see how natural they will get into a squat, so easy. As we age we loose this ability because we stop practicing it, sitting mean sitting on a chair not squatting down to rest, over time it stiffen our body making us less flexible and mobile. Doing the squat position frequently will reverse this, the video show lots of ways to practice to be able to get into a squat again.
Strenght side do have many good videos, I like that channel.
