Ever feel like you have thunder thighs? Squats are a great way to change that! Start with your legs shoulder width apart. Keep your abs tight and slowly bend at the knee while lowering your body as if you were sitting in a chair. Like lunges, make sure your knees are not over your toes. Hold the seating position for a couple of seconds, and then slowly move back to starting position and repeat. Start with 15 to 20 reps and move up to 30.
