This application is built around the famous abdominal vacuum exercise, which allows you to train the internal muscles of the abdomen. If you want to reduce a bulging or drooping belly, to make your waist narrower, then this application is for you. The application includes three difficulty levels, each of which is designed for 14 days. Each day there are only five sets of exercises that you can do at any time. In total, you will spend no more than 7 minutes per day. Convenience lies in the fact that there are no fundamental differences in the exercise while lying, standing or sitting. Therefore, you can do it anywhere.
