There are many people who wonder if the contour belt placed around the stomach could really give a flat stomach. But the fact is that these belts helps the muscles to contract and are real cool devices. This belt could be worn and all kinds of work around the house could be done along with the contraction that is taken care by the belt worn. There is also another fact that has to be noted very carefully. This contour belt does not reduce fat. It only contracts the muscles. This method is known as spot-reduction. This method works a group of muscles in a particular area which in turn loses fat from that area. This is the theory of spot-reduction. This contour belt might build the abdominal muscle. When these muscles are built the fat in that region is got rid off. So people generally lose fat and build their abdominal muscles.
