Besides just continuing to lose weight you can also do the stomach vacume bellow.

The Stomach Vacuum is an isometric contraction (tenses the muscle without moving it) of the Transversus Abdominus. A stronger Transversus Abdominus can create a stronger Valsalva Maneuver (the powerful exhale necessary to contract a muscle during an intense workload). This is one of the best exercises you can perform to shrink your waistline in a very short amount of time. Many can knock 2 to 4 inches off their midsection in as little as 3 weeks with this technique. Also, building this area of the abdominal muscle will help you gain more control over your "abs" and assist you better in explosive lifts. Stomach Vacuums take practice, but they are extremely effective.

How to do the stomach vacuum

To execute the Stomach Vacuum, stand upright and place your hands on your hips, and exhale all the air out of your lungs, completely. Expand your chest, and bring your stomach in as much as possible, and hold. Visualize trying to touch your navel to your backbone. One isometric contraction of "X" seconds is one repetition.

Once mastered, the Stomach Vacuum can be performed in a standing, kneeling, seated, and lying position. Now you will have no excuse to avoid abdominal training if you are stuck in traffic.

As an added bonus, you can use the Stomach Vacuum when doing your regular abdominal work. Focus on pulling in on the Transverse Abdominus. Simply do this by pulling in your stomach as far as you can and flex your groin muscles, as if you are trying to stop the flow of urine.
