A wall-assisted squat drill teaches you to use both hips and knees while keeping your pelvis stable. The wall prevents forward movement, forcing you to open your hips and push your knees forward instead of collapsing into it. The key is coordinating hip and knee movement together.
We want to teach the body how to squat using both our hips and our knees and slaying the wall. So here you can see I can't move forward. If I move forward, I'm going to nosedive straight into the wall. So as I move, it forces me to get down. I have to open up my hips. Now it creates that kind of nice dynamic between I push my knees forward, but I also have to stick my hips out at the same time, which creates this nice stability through my pelvis. So you can see I'm pushing my hips out, I'm pushing my knees out. My knees are also coming forward, and then I'm straight back up.
