Elevation Training Mask

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. Benefits: increases anaerobic thresholds, energy levels rise, mental and physical stamina increase, mental focus becomes better, learn to control breathing against resistances, and switching nose pieces allows for increased resistances. 3 Holes Open = 1x Restricted breathing. 2 Holes Open = 3x Restricted Breathing. 1 Holes Open = 9x Restricted Breathing.
