Start sculpting now for bare-it-all confidence all year long. by Jeanine Detz

IF YOU STARTED OUR BIKINI BODY COUNTDOWN last month, you’re looking pretty hot—but don’t stop now! Stick with the program and you’re guaranteed to reach your get-in-shape goal (if you’re just starting out, dive right in). This workout, designed by the fitness team at Cal-a-Vie Health Spa in Vista, California, shakes things up (crucial for keeping those results coming) by challenging your balance. You’ll perform some exercises on a Bosu balance trainer or while standing on one leg, which forces your muscles to work harder to stabilize you. It will feel tougher than last month’s plan, but with every rep, you’ll be one step closer to your dream body.
