EXPAND A LUNG

The Expand-A-Lung® offers the widest range of inspiratory/expiratory resistance levels to meet anyone's needs. From low resistance for respiratory training, gradually increasing to a high resistance level for competitive athletes. No other breathing trainer product can achieve this range with a single model... The Expand-A-Lung® Research supports that this breathing exercise significantly improves the strength of respiratory muscles, and increases the volume of lung oxygen intake. The end result is deeper, easier and better breathing for a superior endurance performance and longer breath holding capacity.
