Evija Polakova

Evija Polakova is an Oxygen Advantage Advanced Instructor, multi-sport World Championship athlete, currently competing in HYROX, freediver, and former military Air Traffic Control Chief with a deep interest in human performance and adaptation.

Her experience across endurance racing, functional fitness, freediving, cold exposure, heat, high-pressure environments and international competition led her to explore one fundamental question: how can we get more performance from the body we already have?

Through Oxygen Advantage, Evija combines functional breathing, breathing mechanics, CO₂ tolerance, recovery strategies and nervous-system regulation with practical performance training. Her approach is not limited to elite athletes. She works with anyone looking to become more capable - from improving exercise performance and recovery to reducing breathlessness during everyday activities, preparing for challenging environments, or learning to stay composed under pressure.

Evija believes that better performance does not always require working harder. Often, it starts with understanding the systems we already have and learning how to use them more efficiently.

Her philosophy is simple: you don't need a new body - you need better tools to use the one you already have.
