How to do it: Stand tall with your feet shoulder-width apart. You can hold your arms straight out in front of your body at shoulder level or cross your arms over your chest as shown. Lower your body into a squat by pushing your hips back and bending your knees. Hold this position for 30-60 seconds, and then slowly push yourself back to the starting position. Repeat 3 times total.
Brace your core in tight and keep it that way the entire time, and keep your weight on your heels, not your toes. You should be able to wiggle your toes at any time during the hold.
