THE #1 CHOICE OF THE L.A. TIMES REVIEW

As every competitive athlete knows, the body's demand for oxygen substantially increases during any form of high intensity exercise. VO2 Max defines the climax of muscle oxygen delivery before CO2 levels rise and muscle performance diminishes.

The "EXPAND-A-LUNG" inspiratory/expiratory breathing resistance exerciser is a breakthrough product for respiratory fitness training. Research supports that this type of exercise significantly improves the strength of respiratory muscles, and increases the volume of lung oxygen ventilation. The end result is deeper, easier and better breathing for superior performance.

COMPETITIVE ADVANTAGES VS. OTHER PRODUCTS (Compare and Save)

DO NOT BE CONFUSED BY OTHER COMPLEX AND EXPENSIVE PRODUCTS

Some even offer a product line with several bulky models, each pre-set for a limited level of resistance. They mislead you with false and inaccurate information in order to justify their multiple models, high prices and complex exercise instructions.

ONLY THE EXPAND-A-LUNG OFFERS THE SIMPLEST AND MOST EFFECTIVE DESIGN

The Expand-A-Lung provides both inspiratory and expiratory resistance for inhaling and exhaling. You also have 100% flexibility to control all levels of resistance by simply opening or closing the adjustable resistance valve. Furthermore, the Expand-A-Lung is superior in the following:

The Expand-A-Lung offers the widest range of 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 product can achieve this range with a single model.

The Expand-A-Lung is only 4" tall. You can take it anywhere, and use it anywhere. (Pocket Size)

Only one moving part. Turn the valve to the left to decrease the air flow in order to create more resistance. Turn it to the right for the opposite. (See exercise instructions tab)

Heavy duty plastic construction and 100% rust proof. You can run it over with your car, and it will not break! ( Don't try this with the competitors' devices )

The flexible long bite silicone mouthpiece is the most comfortable and provides the best fit and seal. Once in your mouth, you don't even need to hand hold it unless you want to change the resistance level.

$30.95 ($34.00 for international orders), includes shipping & handling.

5 yr. Full Warranty for parts and labor.

In addition, only the Expand-A-Lung offers a risk free guarantee!! If for any reason you're not satisfied, just return it for a full refund within 30 days.
