The altitude mask works by limiting the amount of air you breathe in during exercise. When you wear the mask, you will notice that breathing becomes a little difficult. This happens because the mask has adjustable air vents. These vents control... how much air enters your lungs. When the vents are more closed, less air comes in, and your lungs must work harder. This extra work helps build strong breathing muscles, just like lifting weights builds strong body muscles.
