When wrapped around the stomach, the abdominal muscles will similarly contract and relax, and in the end, firming up.

The belt has different intensity levels ranging from 1-100. Beginners should start at the lower levels and gradually increase the intensity. It should be noted, however, that the Flex Belt is no miracle device and that it is designed to firm and tighten your muscles over time, not overnight. The more toning you need, the longer you will need to use the belt to get the desired effects.
