Expand-A-Lung Sports Breathing Exerciser

The Expand-A-Lung Inspiratory/Expiratory Breathing Resistance Exerciser will provide two very important benefits. IMMEDIATE BENEFIT: It will open the airways into your lungs that have been partially obstructed over the years, due to natural aging, poor physical condition and smoking (if applicable). LONG TERM BENEFIT: It will target and develop the respiratory muscles (the diaphragm and intercostals) to help you breathe more volume of air/oxygen into your lungs, and to exhale more carbon dioxide out of your lungs. THE END RESULT IS DEEPER, EASIER AND BETTER BREATHING FOR A MORE RELAXED AND SUPERIOR ENDURANCE PERFORMANCE, WITH LONGER BREATH HOLD CAPACITY AND LESS SHORTNESS OF BREATH. This is the ideal breathing trainer for athletes and COPD patients, and Ranked #1 by the LA Times Review.
