TIME IT TAKES 30 minutes
HOW OFTEN Do these moves 3 to 5 times a week. For best results, warm up -- cycle, jog, or march in place -- for 5 to 10 minutes first.
SEE RESULTS IN 3 to 4 weeks, especially if you combine this workout with cardio and a healthy diet. At the end of this nine-week program, you'll look more sculpted, feel tighter -- and you may even lose 3 to 5 pounds.
EQUIPMENT A pair of hand weights (we used 8-pound ones) and a fitness ball (about $15; www.performbetter.com).
TO KICK IT UP A NOTCH At the end of 9 weeks, try increasing the weight and adding on another weekly session.
