What Our Students Say

Functional Breathing Training Certification
Jennifer Wendland Three times medalist at freediving world championships, multiple national champion and record holder in freediving,
diving 120m deep on a single breath of air

As an elite freediver I have always been aware of the benefits of correct breathing. This book was inspiring me to spread the message to family, friends and colleagues. Especially the fact that breathing less, not breathing more, will provide better oxygenation is a revelation for most of them. Many of them were able to reduce their stress levels and even anxiety through correct breathing.

Andrew Kacsor Head Strength & Conditioning Coach for the KRS Vanke Rays

The Oxygen Advantage has helped my Olympians become more aware of their breathing. We practice nasal breathing during foam rolling, warm ups, cool downs and during certain prescribed exercise. I would highly recommend Oxygen Advantage to any coach looking to get any additional benefit for their athletes.

Connally McKay Head Rugby Coach, Texas

I am a 20 year rugby player here in the US, and I am the head coach for a major university in Texas. I am 39 years old, and I cannot think of a single thing in my entire life as an athlete that has benefitted and increased my fitness as much as this book has for me. I have since suggested it to two teammates, and they are having similar results. I am going to be honest, this should be required reading for every aspiring or current athlete, and every organized sports team should require all their athletes to read it. My BOLT score started out at around 10, and after a few months of doing the exercises I am at 40. My sleep has improved, and although…

I have taken the Oxygen Advantage Instructor course and can’t say enough good things about it! I have been taping my mouth for my strength training sessions as well as my Tactical training. I have been playing with the knowledge Patrick McKeown has so willingly shared and began experimenting with my Team. The conditioning results have been exceptional but I expected that based on what I learned in the course. Using OA for the reduction of stress in SWAT and other High Stress Law Enforcement activities is what I am most interested in now and I have a lot to work with thanks again to Patrick McKeown. For those out there who are considering taking the course do yourself a favor get off the fence and do it. Money well invested in your health!

Julien Billaut Working for Australian Canoeing and the New South Wales Institute of Sport as a Canoe Slalom High Performance
Coach towards Tokyo 2020

Mastering one of the most powerful mechanism in our body can have a tremendous impact on both well being and performance. Because we breath 24/24, breath training is potentially endless. I have been looking for a technique that could effortlessly trigger diaphragmatic breathing to improve the mind/ body connection. Thanks to the Oxygen Advantage, I have discovered that nose breathing and breath holds could also enhance the fitness level of my athletes through simulation of altitude training. Moving towards the 2020 Olympic Games in Tokyo, we have now integrated the Oxygen advantage breathing techniques into our daily training and recovery.

Patrick’s book, The Oxygen Advantage® is a godsend for anyone wishing to improve their performance in a way that doesn’t involve hours of strenuous workouts, drills, and endless miles of running. I’ve been doing nose breathing for the past ten years and it has totally revolutionized my running and seriously dropped my effort levels… at every speed! It’s simple to incorporate into your training and your daily life. and the results are astounding. I now recommend it in all of my running classes and training programs. Every runner or athlete should have this book. If you’re not breathing right, you’re working too hard.

The Oxygen Advantage , which is an extension of Patrick McKeown’s work as a Buteyko coach, is one strategy that I believe should be included in your health habit arsenal. There simply are no downsides that I can identify and there are massive upsides. I use it personally, and would strongly encourage you to apply it to your life so you can reap the rewards.

Why Invest In Breath Training?

The body can survive for days without water and weeks without food, but without the breath, it will die within minutes. The breath is closely connected with the heart, and its relationship with the nervous system is so direct that different responses are triggered depending on whether you are inhaling or exhaling. As those skilled in ancient contemplative practices have long known, the breath influences every part of the human experience.
Functional breathing often forms the missing link in terms of fitness and quality of life. It’s cost-effective and suitable for everyone. Despite this, breath training has nowhere near the same following as many mainstream diet and fitness trends. While most people will adapt other aspects of their lifestyle to promote better wellbeing, fitness or mental health, they often don’t think to adjust their breathing.
When focus is drawn to breathing, very few health and fitness professionals are trained to accurately identify dysfunctional breathing patterns and habits, or to give instructions that correct them. With the best of intention, they often lack the tools to help their clients learn practices consistent with physical and mental health. Instead of looking to the root cause of a problem, teaching is often symptom-led. It’s time to change this.
As awareness of functional breathing begins to gather pace in sport and in the wider community, this is the perfect time to gain practical, knowledge that will be relevant for you and your students for the rest of your life. Once certified, you will be able to apply your skills anywhere, any time, making a huge, quantifiable and immediate difference to your clients’ lives. And you will earn a great living in the process.

A Few Facts About Breathing

Every single person breathes, all day, every day. It’s fundamental to life. While it might make sense that elite athletes or people in high-pressure jobs could profit from some sort of extra breath training, surely it’s nonsense to suggest that breathing itself is the root cause of problems in the wider population?
The truth is, functional breathing training is relevant for everyone because:

Breathing pattern disorders affect 9.5 percent of the adult population. In people with asthma, its 29 percent, and 75 percent of people with anxiety have dysfunctional breathing. (Jones et al., 2013/Thomas et al., 2001)

Slow breathing at six breaths per minute has been found to optimize heart rate variability (HRV), respiratory sinus arrhythmia RSA), baroreflex (blood pressure receptor) reflexes, gas exchange in the lungs, and to activate the calming power of the parasympathetic nervous system via the vagus nerve.

Sleep disordered breathing is considered to be a public health epidemic, costing the economy millions of dollars in poor productivity and sick days, and contributing to road accidents and early mortality.

Breathing exercises can help with problems as wide-ranging as performance anxiety, sleep, stress, poor digestion, heart health, hypertension and cognition.

Most of what we know about breathing is wrong. For example we believe that oxygen is good and carbon dioxide is bad. The reality… CO2 is essential for good health and vital to oxygenation of the cells. Without carbon dioxide, the body would be starved of oxygen, whether or not oxygen was available in the blood. (Singh, 2017)

One of the most common breathing pattern disorders is something called chronic hyperventilation. Forget the image of someone puffing furiously into a paper bag – this is long-term over-breathing that causes imbalances in the blood chemistry and factors in many pathological conditions – read that again – poor breathing patterns are an underlying factor in a lot of illness.

Chronic hyperventilation tends to involve fast, upper chest breathing. This triggers the sympathetic nervous system’s ‘fight or flight’ response leading to chronic stress (and many associated physical and mental health disorders).

We often urge our students to take a ‘deep breath’. But without an understanding of what a deep breath actually is and how to explain it, we may be inadvertently causing more harm than good.

Breathing should be through the nostrils, and rarely, if ever, through the mouth. Breathing through the mouth has been likened to trying to eat through your nose!

It is possible to maintain nasal breathing even during intensive exercise such as running. One study found athletes were able to train to 85 percent of VO2 max whilst breathing through the nose (Thomas et al., 2009).

Conditions including asthma, diabetes and epilepsy can often be successfully managed by increasing blood CO2 levels. In the case of epilepsy, hyperventilation has been proven to trigger seizures, and in panic disorder, blood CO2 levels are directly related to the panic threshold.

Study Components

The Physiology of Breathing Explained (Nine Lessons and Exercises)
Physiology is the science of the mechanical, physical, and biochemical function of the body. It connects medicine, science and health, and provides parameters in which it becomes possible to understand how the human body adapts to stresses, physical activity and disease.
The physiology of breathing encompasses the role of breathing muscles (of which the diaphragm is primary), functional airways, blood chemistry and gas exchange with the atmosphere. When these aspects are fully understood, it is easy to adapt respiratory behaviors to voluntarily control the physiology – for example, reducing sensitivity to blood CO2 or altering levels of blood gases. In studying the physiology of breathing, you will learn about:

How (and why) to influence the autonomic nervous system

What Breathe Light really means and how it impacts the body

Why breathing ‘hard’ causes poor oxygenation of the cells

The importance of nasal breathing during both inspiration and expiration

The effects of poor breathing patterns, long and short-term

How to reduce breathlessness in sports

The benefits of making the switch to nose breathing

How to unblock the nose

What the oxygen hemoglobin dissociation curve is and what it means for your students

The term ‘breathing exercises’ encompasses a vast array of potentially confusing practices. The exercises used in the Oxygen Advantage® are designed to work with the body’s physiology and biochemistry. You’ll learn a series of straightforward, safe, functional breathing exercises – the same exercises that Patrick uses with his clients every day. You will also discover how to apply the Body Oxygen Level Test – BOLT – a measure of functional breathing and an index of progress.
