Yes. The human body increases oxidation itself with constant exercise and proper breathing. When the body undergoes exercise, it’ll eventually hit a wall where it cannot get enough oxygen, so cells begin to ferment and create lactic acid to slow you down to not hurt yourself. However, with enough time, your body will become more efficient at the various process that allow oxygen to pass into cells, allowing you to go further and do more. The acid does not cause this.

This is why athletes are banned from breathing pure oxygen before races, or getting quick blood transfusions of oxygenated blood.

He’s trying to claim that it’s his laughable “breathing exercises” doing this.

Second, those studies are all but useless. I read through a handful, and they would barely qualify for a conceptual piece. The most up to date one is a small study from 1998 with 38 people, that is laughable and obsolete in the realm of science. They are also trying to sell their “program”. They are frauds. Don’t waste your time.

Just go exercise once a day and don’t bother with the waste of time.

And lastly, if it was real. Why isn’t every Olympics team doing this? Why aren’t China, Russia, and the US training their soldiers and cosmonauts to do this? It’s a scam.
