Oxygen Advantage

A contemporary breath-training system by Patrick McKeown, aimed mainly at athletes, using nasal breathing, breath holds, and CO₂-tolerance training to improve breathing efficiency. It builds on the Buteyko Method and uses the BOLT score to track progress. Exercises include nasal breathing during exercise, breath holds while walking and simulated altitude training. Breath-hold training should be practiced gradually and never in or near water. McKeown described the approach in his 2015 book The Oxygen Advantage. Research on the programme itself is limited, although studies on nasal breathing and breath-hold training in athletes cover parts of it.
