Altitude masks are beyond useless and actually reduce results
You want to live at high altitude to get the increased RBC benefits but train at low altitude to get a better training session.
Altitude masks do not help in any way at all as they do not increase RBC count. You need a shift in pressure to get the benefits which is why top athetes sleep in specialized chambers.
All altitude masks do is force you to reduce your training intensity which in turn leads to less results. You may as well burn your money.
