The Expand-A-Lung® inspiratory/expiratory breathing resistance trainer is a breakthrough product for improving endurance through better breathing and lung function. 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.
As every competitive athlete knows, the body’s demand for oxygen substantially increases during any form of sustained high intensity exercise. VO2 Max defines the climax of muscle oxygen delivery before CO2 levels rise. At this point, muscle performance decreases and shortness of breath increases. This is what the Expand-A-Lung® targets and improves.
The Expand-A-Lung® offers the widest range of inspiratory/expiratory resistance levels to meet anyone’s needs. From low resistance for respiratory rehab patients, gradually increasing to a high resistance level for competitive athletes. No other breathing trainer product can achieve this range with a single model.
It is also an excellent exercise for COPD.
