Stand with your head facing forward and your chest held up and out.
Place your feet shoulder-width apart or slightly wider. Extend your hands straight out in front of you to help keep your balance.
Sit back and down like you're sitting into an imaginary chair. Keep your head facing forward as your upper body bends forward a bit.
Lower down so your thighs are as parallel to the floor as possible, with your knees over your ankles. Press your weight back into your heels.
Squat down until your hip joint is lower than your knees.
Keep your body tight, and push through your heels to bring yourself back to the starting position.
