If you experience uncomfortable shortness of breath, a regular lung work-out could help. By inhaling and exhaling for a few minutes a day against modest resistance, your lungs have to work a little harder and may become stronger. The work-out may also improve oxygenation of the blood and diminish those dull headaches caused by shallow breathing. The exerciser lets you monitor respiratory strength and lung capacity by seeing how far up the clear chambers the three balls rise as you exhale.
