My friend told me the other day that not only do the pro swimmers train in the high-altitude zones with low oxygen level, but supposedly some train in swimming facilities where they lower the oxygen level some way.Sounds kinda hard to believe.Is that even true or possible to lower the amount of oxygen in pools?Or is it just some BS?
