Get Flat AbsThe foods, the moves and a quick trick to help you lose the muffin-top now that it's beach season.

FUEL UP Foods rich in protein help you build muscle, while soluble fiber - found in oats, beans, fruits, and veggies - shrinks belly fat. A study from Wake Forest found that for every 10-gram increase in soluble fiber people ate daily (about two small apples, a serving of oatmeal, a half cup of pinto beans, and a half cup of peas), their belly fat decreased by almost 4% over five years.
FIGHT WITH FIBER Adding ground flaxseed to your diet - mix a teaspoon or two into cereal or yogurt - helps prevent constipation. (It's hard to have flat abs if your pipes are backed up.) To avoid stomachaches, increase fiber slowly and up your water intake, advises Jessica Crandall, R.D., spokesperson for the Academy of Nutrition and Dietetics.

GO FOR A FAT BLAST In a Duke University study of 196 sedentary, overweight adults, aerobic training significantly reduced deep belly fat and also burned more visible midsection flab. To maximize the benefit with a minimum time commitment, try interval training, suggests exercise physiologist Jessica Matthews of the American Council on Exercise. Start with a 1:2 ratio (jog 30 seconds, then walk briskly for a minute), aiming for 150 minutes weekly.
POSTURE PERFECT Standing tall, with tummy and butt tucked in, automatically makes your front look flatter. These two moves help you pull it off. Do each two to three times per week; work up to three sets of 12 reps.
Glute Bridge: Lie on back with bent knees, feet on floor. Lift butt, drawing pelvis to the ceiling without arching back. Lower butt down slowly.
Bird Dog: From all fours, extend one arm and the opposite leg to shoulder and hip height simultaneously, keeping shoulders and hips squared to the floor. Lower slowly to start, and repeat on opposite side.
