hi sebastien, i have a few questions:

first of all, are you talking full hyperventilation, or moderate hyperventilation?
and also, how long should the holds be, in terms of difficulty.......i am not sure if it would be best to do 90% holds or 100%, and also the length in between holds?

Another question i have is although i read the article, i did not understand fully what the training will do. Will it just increase my low o2 tolerance?

thanks for your time,
