Breathing training works just like training any other muscle group with resistance - your muscles become faster, stronger, and more efficient. The training system consists of a breathing training device and a mobile application. The breath trainer measures your breathing data, such as inspiratory and expiratory strength and vital capacity. The data is processed and visualized in real-time on your smartphone, allowing you to receive live feedback and guidance, and track your progress over time. The app offers over 20 interactive training programs designed to improve your breathing capacity and respiratory muscles. The app can be set to German and many other languages.
