A Complete Guide to Becoming a Certified Breathing Instructor

A Complete Guide to Becoming a Certified Breathing Instructor Oxygen Advantage
It’s always worth paying attention to something we often take for granted: how we breathe, because it shapes how we feel, think, and perform daily. This is why breathwork is becoming an essential part of modern health and performance training that improves your health.

If you are thinking about learning breathwork or teaching it, you are likely asking a few key questions. What is breathwork training? How do you get certified? And which path actually works? 

This guide gives you clear answers, grounded in the Oxygen Advantage® Method, a structured, science-based approach focused on improving everyday breathing in a measurable way. You will learn how training and certification work, and how to get started.

What Is Breathwork Training?

Breathwork training is often seen as learning techniques such as slowing the breath, deepening it, or using patterns for relaxation or performance. But real breathwork training goes further than techniques. It is about understanding how breathing affects the body and mind, and how to change it in a way that creates lasting results.

Breathing is not something you only do during a session. It is a continuous process that influences oxygen delivery, circulation, nervous system balance, sleep, and energy levels throughout the day. If everyday breathing patterns remain inefficient, they will continue to affect how a person feels and performs.

Effective breathwork training focuses on improving that baseline. It teaches you how to assess breathing, understand what is driving it, and apply the right methods to improve it over time.

This is where Oxygen Advantage® stands out. It is built around three key areas of breathing: biochemical, biomechanical, and psychophysiological. These work together to improve how the body functions as a whole.

Developed by Patrick McKeown, Oxygen Advantage® combines functional breathing, carbon dioxide tolerance training, and nasal breathing into a clear, science-based system. It gives you a practical framework you can use with confidence. 

Who Is Breathwork Training For?

Breathwork training is used across many professions because breathing influences every system in the body. Most people come to it after seeing results for themselves or their clients, but without a clear structure to apply it consistently.

Oxygen Advantage® provides that structure. It is built around three key areas: Body, Mind, and Sport, allowing breathwork to be applied with precision across physical health, mental wellbeing, and performance.

It is particularly relevant for:
  • Body: movement and health professionals, such as yoga teachers, physiotherapists, and manual therapists, who want to address the root cause of tension, posture, and recovery
  • Mind: coaches and wellness practitioners supporting stress, sleep, and emotional regulation with a more structured, measurable approach
  • Sport: coaches and performance professionals looking to improve endurance, recovery, and focus under pressure
It is not limited to professionals. Many people start by improving their own breathing, sleep, and resilience. As they experience changes, they see how these tools can support others. As there are a number of short online breathwork courses to improve your health.

This is where the shift happens. Breathwork moves from something you use occasionally to something you apply with purpose.

Connor Dent, a licensed massage therapist and Oxygen Advantage® instructor, explains the impact clearly: “Now, every session begins not with deep tissue or fascia work, but with the breath.” By starting with breathing, he helps clients downregulate quickly, leading to deeper muscle release, lower pain sensitivity, and results that last.

Anthony Lorubbio, Certified Oxygen Advantage® Instructor and executive performance coach, shares a similar shift, noting that the training “transformed my coaching practice… opening doors I never imagined.”

Across the Oxygen Advantage® community, the setting may differ, but the outcome is consistent: breathing becomes a structured, reliable tool that delivers measurable results.

Why Should You Get Certified in Breathwork?

For many, breathwork begins as a personal practice to improve sleep, reduce stress, or gain control over energy and focus. Over time, the benefits become clear, and breathing shifts from a simple practice to something foundational.

At that point, people want more than techniques. They want structure, clarity, and a deeper understanding of how breathing works to keep improving their results consistently.

For others, the next step is professional. They begin to see how breathwork can support clients, but applying it safely and effectively requires more than personal experience. Certification provides the knowledge and framework to assess, adapt, and guide with confidence.

Oxygen Advantage® supports this progression by offering a structured, science-based system focused on real-world application. It gives both individuals and professionals the tools to improve breathing in a measurable and practical way.

For many, this becomes a turning point. Alice McRae, a Pilates teacher with over 15 years of experience, integrated functional breathing into every class after training and now works with over 90 clients each week, improving both her own health and her clients’ results. 

How to Become a Certified Breathwork Instructor

Becoming a certified breathwork instructor follows a clear progression. Each step builds your understanding, confidence, and ability to apply breathwork in real situations. The goal is to develop a practical skill you can use professionally, not just learn techniques.

1. Understand what breathwork training involves

The first step is understanding what breathwork training actually is. It goes beyond techniques and focuses on how breathing influences the body and mind, including oxygen delivery, nervous system regulation, sleep, energy, and performance.

A structured system like Oxygen Advantage® helps you move beyond surface-level methods. It provides a clear framework so you understand not just what to do, but why it works and how to apply it effectively.

2. Choose the right certification path

Choosing the right course depends on your goals. Some want to improve their own breathing, while others want to teach breathwork professionally or integrate it into their work.

Oxygen Advantage® offers a clear pathway. You can begin with foundational training or move into a more advanced program depending on how deeply you want to apply breathwork across health, performance, or resilience.

3. Start with a foundational course

A Level 1 course, such as the Oxygen Advantage® Functional Breathing Instructor Training, provides the core knowledge needed to begin. You learn how to assess breathing patterns, identify dysfunction, and apply techniques safely and effectively.

This stage builds clarity around real outcomes such as sleep, stress, and recovery. It forms the base for any breathwork instructor certification and prepares you for further development.

4. Practice consistently

Personal practice is essential in breathwork training. Regular use of techniques helps you experience changes in energy, focus, and recovery, which deepens your understanding of how the method works.

This experience builds confidence and makes it easier to guide others. It is a key part of any structured breathwork facilitator training process.

5. Progress to advanced training

Advanced training expands both your knowledge and your ability to apply breathwork in more complex situations. The Oxygen Advantage® Advanced Instructor Training develops this further across the three pillars of Body, Mind, and Sport.

At this stage, breathwork becomes a system you can adapt to different individuals and settings, including performance, stress, and recovery.

6. Complete certification requirements

To get certified in breathwork, you must demonstrate understanding and application. This includes completing modules, passing assessments, and, in advanced training, case studies.

Oxygen Advantage® certifications are designed this way to ensure you can apply breathwork safely, effectively, and with confidence in real-world situations.

7. Start teaching breathwork professionally

Once certified, you can begin working with clients. Breathwork can be integrated into coaching, therapy, fitness, or developed into a standalone offering, such as workshops or group sessions.

Over time, your skills grow. Learning to teach breathwork professionally lets you build a flexible and meaningful career using a science-based, in-demand skill.

After Certification: Teaching and Career Opportunities

After certification, breathwork becomes a practical skill you can apply with confidence in real settings. The training focuses not just on techniques, but on how to work with clients, structure sessions, and deliver clear, measurable results.

Oxygen Advantage® supports this transition by providing structured frameworks, assessment tools, and ready-to-use teaching materials, making it easier to begin working with individuals or groups straight away.
