But here is the key point: Why would you want to run your body at 600 hp rather than 800? And what happens to civilization when we all run at 90% capacity?
When you wear a training mask, your body begins to adapt to the reduced oxygen intake, making your heart and lungs work harder.
Then, when you take the mask off, you’ll get a big boost — your body has adapted to the restricted oxygen and is able to use the oxygen more efficiently, which helps you perform better.
After using a training mask for some time, you may feel like you can run faster, jump higher, or bike for a longer duration. If you’re a competitor, this may give you an edge over the people you’re up against.
