Hello, my name is Marek Kery and I am a personal trainer and OXYGENADVANTAGE instructor currently working in Slovakia.

When I learned about Oxygen Advantage and found out about all the benefits I knew instantly that I want to be part of this.

I have done my Oxygen certification in Slovakia and I am ready to teach clients online and one on one basis both in english and slovak language.

Together we might improve your breathing, increase oxygen supply to cells, improve blood circulation, unblock a stuffy nose, open airways in the lungs, improve blood flow and oxygen supply to the brain, improve sleep, and even bring peace of mind.

Shall we do this?
