Like I said, cardio is still an important (albeit smaller) part of a bikini-ready workout. But for this we're focusing on interval training, which is different from going steady on the elliptical for 40 minutes. Alternating high-intensity exercise with low-intensity recovery periods actually improves the body's ability to burn fat. So in addition to sculpting and weight-training exercises, these bursts of interval cardio will help reduce flab. Take an interval training spin class, or test out an interval course on the elliptical on your own. For the treadmill-lovers, try alternating between 3 minutes of running and 1.5 minutes of sprinting for 30 minutes (or walking and running if you're a beginner).
