Stand facing forward with your chest up. Place your feet shoulder-width apart or slightly wider. Extend your hands straight out in front of you to help keep your balance. Bend at your knees and hips, sticking your butt out like you're sitting into an imaginary chair. Keep your chest lifted and your spine neutral, and do not let your lower back round. Squat down as low as you can, keeping your head and chest lifted. Keep your knees over your ankles and press your weight back into your heels. Keep your body tight, and push through your heels to bring yourself back to the starting position.
