This summer, get the legs that you've always dreamed about. This easy six-week plan will help you score trimmer thighs and a tighter tush, as well as reduce your overall body fat and build lean, calorie burning muscle. Your Challenge coach, fitness expert Jessica Smith, has designed a simple weekly program that will show you how to work your gams the right way to achieve a truly trimmer lower half, while not neglecting your upper body.

How It Works: "Like" SHAPE magazine on Facebook to get daily updates about the Challenge, including a daily motivation tip to help power your leg workout, a daily assignment that will keep you on track and weekly question-and-answer sessions with your coach on Facebook, every Tuesday at 1 pm EST. Each week, you'll have access to a new workout that will grow progressively more challenging as you begin to see results.
