Your Coaches

Gray Caws

Gray is one of the most experienced Master Oxygen Advantage coaches having worked with Patrick McKeown on the very first Masterclass and subsequent Instructor Training in 2016.

He was first introduced to the importance of breathing in sport by England Athletics coach and Cardio Physiotherapist Robin McNelis who taught the importance of nasal breathing and breath rate in running.

Gray has a relaxed, friendly teaching style that works for everyone, whatever level of fitness or experience.

Alongside his Oxygen Advantage certification he is also a Buteyko Practitioner, running coach, UK Level 4 Personal Trainer and teacher of Qigong.

“I love nothing better than to get outdoors and explore. If I need a motivational boost then to be out running, walking, and playing is where I’m at my best.

I believe the best way to optimise your health and fitness is to practise something that you enjoy, keep it simple, focus on the breath, challenge yourself but don’t overdo it!

Training through play allows you to tap into your natural, intuitive flow of breath, energy, and movement.”

Patrick McKeown

Patrick McKeown BA, MA, is considered to be one of the foremost teachers of functional breathing. He has authored eight books, is published in 14 languages and has taught breathing for mind, body and sports since 2002.

He has worked with more than 7,000 clients from children to the elderly, from the most unwell to elite athletes.

He has channelled a wealth of experience, expertise and passion into the delivery of this simple, easy to follow training, in order to share his approach with others, so that many more people can enjoy better health, performance and quality of life.

Frequently Asked Questions

If you’re reading this page, the chances are you’re already more than a little bit interested in the breath and what it can do for you.     

You may already have completed other breathwork training and want to deepen your knowledge and practice.

Perhaps you’ve read an article or book about the breath and want to learn practical ways to apply the science.

Or, since the topic is currently trending, maybe you’ve been asked questions by your clients that you don’t know how to fully answer …

Functional breathing is a vital missing link in fitness, health and quality of life.

It is cost-effective, suitable for everyone and has almost endless applications, without the need for any costly equipment.

Yet most people are unaware that the breath can be trained.

If your energy is low, you might consider taking supplements, changing your diet, drinking more water or pushing yourself to work harder rather than exploring how breathing, sleep and mental stress may be affecting your body.

That’s a lot of money, time and effort when the answer is quite literally under your nose.

Yes, you will be fully certified to teach the entire Oxygen Advantage Programme to your clients, students and athletes.

This certification is for life with no need for renewal of training.

You are, however, encouraged to join our regular live Zoom classes with Patrick as a refresher should you require.

The Oxygen Advantage Programme is based on the two pillars of functional breathing and simulation of high altitude and high intensity training.

Everyday functional breathing has been proven to help with:

  • Overall health
  • Exercise performance and stamina
  • Breathing during Yoga
  • Lower back pain, posture and core muscle strength
  • PTSD, anxiety, depression and panic disorder
  • High stress and mental agitation
  • Energy, focus and concentration
  • Insomnia and snoring
  • Fatigue and mood
  • Rhinitis (stuffy nose and hay fever)
  • Asthma and exercise-induced bronchoconstriction
  • Diabetes and epilepsy control
  • Depression and anxiety in people with comorbid conditions like bipolar disorder, that prevent the use of antidepressant medication

High altitude and intensity simulation breathing exercises have been proven to:

  • Delay the onset of fatigue and lactic acid
  • Improve repeated sprint ability for team sports such as rugby and football
  • Improve respiratory muscle strength
  • Improve aerobic capacity
  • Increase production of EPO (erythropoietin) safely and legally
  • Improve running economy
  • Improve swimming performance
  • Reduce oxidative stress

You receive instant lifetime access to our complete advanced online training portal for instructors, with video teaching modules, recording of your live classes with Patrick, online research library and downloadable PDF of training manuals.

You also receive a hard copy of the training manual and Breathing Cure book by post.

Please allow two weeks from date of registration for receipt of materials.

The live online training comprises detailed instruction in all of the Oxygen Advantage exercises and methods.

You will learn how to put the theory into practice.

You will receive all of the video modules, hard and soft copies of the instructor and athletes’ manuals, fourteen hours of live coaching with Patrick via Zoom and lifetime access to the training portal where you can revisit any of the materials in your own time.

Some Facts About Breathing

Breathing is our first and most fundamental motor pattern. Every single person carries the breath with them every single day.

Yet a surprising proportion of people have breathing pattern disorders, sleep-disordered breathing and a poor understanding of the breath.

While you might appreciate why elite athletes or corporate high-fliers could find breath training useful, it may be less obvious exactly how far-reaching the applications are, and how you can apply them to your work.

Here are some interesting facts about why functional breathing training is relevant for everyone:

  • Breath retraining can be used as a primary or adjunct therapy for physical and mental health conditions including anxiety, panic disorder, depression, sleep apnea, insomnia, hypertension, diabetes, epilepsy, childhood development, behavioural disorders, asthma, menopause, headache, back pain, chronic pain conditions and even some medically unexplained symptoms.
  • Breath training can also be used in sports and endurance training to improve performance by building tolerance to CO2 and reducing the ventilatory response to exercise.
  • The way you breathe influences how your body processes oxygen. Unhealthy breathing can reduce the amount of oxygen that is released from the lungs to the blood, and from the blood to the tissues and cells.
  • Carbon dioxide is not just a waste gas. In fact, it provides the primary stimulus to breathe and plays an important role in the dilation of blood vessels. When you ignore the importance of CO2 in favour of oxygen, you actually prevent the body from properly oxygenating.
  • A low sensitivity to CO2 is beneficial for general health and for sporting performance. Studies have shown that this lower sensitivity is one of the things that separates outstanding endurance athletes from the competition (McGurk et al., 1995). If this sounds complicated, don’t worry. You’ll soon understand what it means and how to apply it.
  • Mouth breathing can restrict the airways, even when you breathe in through your nose and out through your mouth. Despite what many people may tell you, it is not a good idea to breathe like this for an extended period of time. Scientists have proven that it causes the nose to become 200% more congested than when breathing is only through the nostrils (Strohl et al., 1992).
  • Many methods used by clinicians to screen for dysfunctional breathing are ineffective and return inaccurate results (Kiesel et al., 2017).
  • Women who suffer premenstrual syndrome (PMS) are actually experiencing imbalances of blood gases due to cyclical hyperventilation. This means that the breath can be used to alleviate this debilitating condition (Chaitow, 2012/Ott et al., 2006).
  • Slow breathing can help in the treatment of insomnia. Scientists believe it represents a better long-term solution than the over-prescription of hypnotic drugs (Ravinder et al., 2019).
  • Asthma is very common in elite endurance athletes. A Swedish study of 38,603 adults who were participating in endurance competitions reported that 12% had asthma – a far higher figure than the 4.3% of 18 to 45-year-olds worldwide reported by the Global Asthma Report 2018 (Näsman et al., 2018).
  • A significant number of unrelated studies have drawn the conclusion that practising a breathing rate of six breaths per minute activates the ‘rest and digest’ branch of the autonomic nervous system via the vagus nerve and provides the best conditions for lung health, oxygenation, heart health, resilience and healthy blood pressure (Russo et al., 2017).
  • The diaphragm is the main breathing muscle, and it’s also vital for postural control. When you breathe in, the diaphragm descends, and a positive pressure is generated in the abdomen. This ‘intra-abdominal pressure’ acts like an inflated balloon, stabilising the spine and the pelvis (Key, 2013). This is really important for functional movement, for understanding the core, and for injury prevention.
  • It is possible to simulate high altitude and high intensity training with the use of breath-holding exercises. Training in this way can produce better aerobic and anaerobic capacity, allowing the body to stimulate anaerobic glycolysis (the process by which blood sugar is broken down to form energy-giving lactose), improving the strength of the breathing muscles and tolerance to breathlessness and reducing the ventilatory response to hypercapnia and hypoxia. It gives increased VO2 max and produces better running economy, better repeated sprint ability for team sports and better-sustained fitness during rest or injury.
