We have begun handling “BreatheHOME,” a core-strengthening breathing apparatus for sports developed by Gelmed, a world-class breathing apparatus manufacturer. Unlike conventional strengthening devices, it features the ability to train not only the power to inhale but also to exhale. The training level can be adjusted to 10 levels, and by doing it twice a day for 5 minutes, the muscles that support the trunk can be effectively strengthened, allowing you to move up one level from “abdominal breathing” to “abdominal pressure breathing. Please consider it!
