At the gym: Training
Women who hit the gym and watch calorie intake reduced ab fat-cell size by about 18%, making them more successful at tummy trimming than those who just dieted, according to a Wake Forest University study.
Scott Fisher, RD, director of the Fitness Center at Fairleigh Dickinson University, says the more weight-bearing the exercise, the more calories torched from your midsection. So walk, run, or add some jump roping to your usual routine.
Research in the American Journal of Clinical Nutrition showed that women who did full-body strength-training twice a week decreased overall body fat and didn't gain as much ab fat as those who didn't.
Do more. Duke University researchers found that jogging 20 miles per week burns more belly fat than covering 12 miles per week.
Work in intervals. Women who did 20 minutes of interval training three times a week lost more belly fat than women who logged 40 minutes of moderate cardio three times a week, according to an Australian study.
