Expand-A-Lung Breathing Resistance Exercise


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.

It is a fact that breathing resistance exercise will develop stronger lungs, and this in turn can provide an endurance advantage for any sport. It can also be beneficial to people who suffer from shortness of breath, due to natural aging and respiratory disorders.

Our breathing exercise is modeled after the relaxing and slow breathing exercises used in Yoga and Tai Chi. Our exercise promotes relaxation and proper breathing technique, but with the addition of adjustable resistance to strengthen your lungs. It is a slow and continuous flowing breathing resistance exercise, inhaling and exhaling through the comfortable mouthpiece. This is by far a more complete and effective breathing exercise than the one provided by threshold machines that separate and isolate inhaling from exhaling during the exercise

How does the Expand-a-Lung Work?

Breathing Resistance Exercise

The flow of air in and out of the alveoli is called ventilation and has two stages: inspiration (or inhalation) and expiration (or exhalation). To accomplish this, the whole thorax moves and changes size, due to the action of two sets of muscles: the intercostal muscles and the diaphragm. These are the muscles that are strengthened by using the Expand-A-Lung Breathing Resistance Exerciser.

Inspiration (Inhaling) with resistance:

  • The diaphragm contracts and flattens downwards

  • The external intercostal muscles contract, pulling the ribs up and out

  • The volume of the thorax increases

  • More air is delivered deeper into the lungs

  • The lung and alveoli volume increases

  • More oxygen is absorbed

Expiration (Exhaling) with resistance:

  • The abdominal muscles contract, pushing the diaphragm upwards

  • The internal intercostal muscles contract, pulling the ribs downward

  • This gives a larger and faster expiration

  • More CO2 is expulsed

In essence, you inhale more oxygen, and you exhale more carbon dioxide. The result is a substantial improvement in shortness of breath and endurance through better breathing.

All is done naturally, with the help of the Expand-A-Lung Breathing Resistance Exerciser.
