It's your foundation, so treat it right with these core-strengthening moves from Tracy Anderson.
The truth: The belly is a bad place to pack on pounds. That’s because excess visceral fat—found deep within the abdomen—increases major health risks (heart disease, type 2 diabetes, even dementia). One study revealed that normal-weight women with bigger bellies had a 48 percent higher risk of premature death than their slim-stomach counterparts.
Luckily, you can take control of that gut. "Cutting portion sizes, reducing saturated fats, and exercising more will all help," says Roshini Rajapaksa, MD, associate professor of medicine at NYU School of Medicine.
Adds Cynthia Sass, RD, "Foods rich in monounsaturated fats, such as avocados, extra-virgin olive oil, and nuts, have been shown to help ward off belly fat, as have beans, lentils, and peas."
Performing ab-centric moves is also key, says star trainer Tracy Anderson. But you’ve got to hit the muscles from every angle. "It’s not just about the front of the abs, the rectus abdominis," she explains. "You have to also get the obliques, the transverse abdominis—which acts as a girdle—and the lower back muscles working together."
This series does just that. Do 30 reps of each move in the series on one side, then repeat the sequence on the other side. Don't forget your 30 to 60 minutes of cardio six times a week to watch your dream abs take shape.
