Squat to knee up

Instructions

Adopt a hip-width stance with the feet naturally turned out, head facing forward, hands on your head.
Lower your butt until your thighs are parallel to the floor, keeping your back straight. Your knees are following your toes direction and your hips are slightly moving backward, as if you're sitting on a chair.
Go back to the starting position, then raise your knee to the side, trying to touch it with your elbow.
