  • Breathing exerciser boosts respiratory performance

How it works: after positioning the soft mouthpiece between the teeth and gums and biting down to create an airtight seal, the user breathes in sharply and continues to breathe in hard for as long as possible. Then the breath is slowly exhaled. When repeated 25 times, twice daily, for at least a month, the exercises should noticeably increase breathing strength. As improvement occurs, the user can increase resistance by simply turning one or both parts of the device: the end cap (which holds a lightweight ball) and the valve sleeve. Measuring 5 by 2 by 1-1/4 inches.
