Stand with your feet shoulder-width apart, eyes facing forward, shoulders back, and chest out. Extend your hands straight out in front of you to help keep your balance. You can also bend the elbows, clasp the fingers, or hold your arms up.
With a slight bend at the knees, send your hips back as if you are about to sit in a chair. Keep your head facing forward as your upper body bends forward a bit. Rather than allowing your back to round, let your lower back arch slightly as you descend.
Lower yourself down until your thighs are parallel to the floor, pressing your weight back into your heels.
Keep your body tight, and push through your heels to bring yourself back to the starting position to complete one rep.
