Elevation Training Mask mimics the effect of High Altitude Training. When top athletes want to improve in their performance, they go to high altitude levels to train. When they return to sea level to compete, they are performing much stronger, faster, and have more endurance due to the many benefits of elevation training.
Elevation Training Mask is great because it regulates how much air you can breathe in - making it so that you breathe less oxygen - in turn, making the air thinner (due to the low oxygen intake it's similar to altitude training). With reduced oxygen consumption the human body changes in several ways. The production of red blood cells and new capillaries (small blood vessels) increase the transfer of oxygen from the lungs to the rest of the body more efficiently.
The Elevation Training Mask comes with 3 nose pieces giving you 3 levels of intensity with one mask.
