Stand with your chest tall and your feet shoulder-width distance apart and facing slightly outward.
Hold your hands at chest level (or at your hips), and bend your knees as you lower into a squat like you're sitting in a chair, shifting your hips and butt back.
Keeping your chest lifted and your knees over your ankles, push through your feet to hop them together into a narrow squat with your feet together.
Hop your feet back out to your basic squat, then push through your heels to bring yourself back to your starting position.
