Melt Your MiddleFollow this interval-training program three times a week after your core workout. It'll fire up your metabolism and burn off the fat that's hiding your abs. Intervals are short bursts of maximum-intensity effort—you're doing it right if you can't carry on a conversation—separated by periods of easy-pace recovery. In an Australian study, women who cranked out high-intensity interval training three days a week for 15 weeks dropped significantly more weight than those who exercised for the same period of time at a lower intensity.
For this interval workout, remember to include an easy 3- to 5-minute warmup and cooldown. You can run, bike, or use the cardio machine of your choice.

Here is the workout:
Basic Move: Plank
Starting at the top of a pushup position, bend your elbows and lower yourself down until you can shift your weight from your hands to your forearms. Your body should form a straight line. Brace your abs (imagine someone is about to punch you in the gut) and hold for 60 seconds. If you can't make it to 60 seconds, hold for 5 to 10 seconds and rest for 5 seconds, continuing for 1 minute. Focus on form: Don't drop your hips or raise your butt.
