It’s time for Breathtaking self-mastery 

Improve sleep, support immunity, release stress, enhance athletic performance, empower leadership, strengthen focus… all of these and many more are just a few breaths away. 

This full-scale Online Breathwork Masterclass will teach you key principles to optimise your life through the art of breathing. After this you will be able to understand and apply any breathing technique or method out there, and know how to access desired outcomes through conscious breathing.

The course  is packed with theory, and application. It’s a great fit for anyone who is serious about mastering their breath. Both for personal practitioners and coaching professionals who want to expand their toolkit and deepen their understanding and teaching.

Beyond breath, you will learn to look at health and well-being from an all-inclusive biohacker perspective that will help you self-experiment, self-actualize and self-quantify real life results. Not only is this a powerful stand-alone course, it’s also the prerequisite for joining our Level 2 Certification. 

Every. Single. Breath…

💆‍♀️ Massages each organ in your abdominal cavity through movement of the diaphragm.
🦠 Exchanges vital information between your environment and your immune system.
⚡️ Informs your nervous system on which functions to activate or suppress.
💡 Determines the quality of your thoughts, attention and actions.
💓 Is electrically wired through the heart to influence every beat.
✨ Sets the pace for how much calm and relaxation you experience.
🧬 Influences the level of metabolism in your mitochondria.
🧠 Pulses your brain and spinal fluid up and down.
🧘‍♀️ Is an opportunity to come back to your center.
🎤 Is a tool to express yourself authentically.
👑 Could be under your conscious control.

The biohacker perspective looks at the human experience from a systematic point of view. The way you feel, your level of energy, the quality of your thoughts, and anything you experience is shaped by the state of your biology.

The problem is that 95% of that biology works autonomically – beyond our conscious control.

And it just so happens that the breath is the ultimate doorway into our subconscious. It is the most important biological function we have. Don’t believe me? Try to do all those other important things while you hold your breath 😉

So in stead of getting caught up in the chaos of breathing techniques, methods and protocols that pop up everywhere, a Breathwork Biohacker studies the core principles of physiology, metabolism and the nervous system with the aim of finding hacks and shortcuts towards more awareness and better performance. To then create a targeted breathing intervention to see instant results.

And that’s exactly what this course is about!

      Kasper van der Meulen

      “The Breathwork Biohacker” will be your teacher

      My work is devoted to teaching the core principles at the source, without getting lost in the details of methods, techniques and protocols. To lift the veil and fade the boundaries, and to connect the dots between ancient practice, modern science, human performance, personal healing and expanding consciousness. 

      Over the past decade I’ve explored and experimented with every human optimization technique I could find. I’ve been honoured to work closely with some of the key influencers in this new wave of modern, science-based breathing. I’ve been fortunate to learn from experts, scientists, doctors, and teachers from many disciplines about how breathwork relates to wellness, consciousness, performance, and human optimization. I’ve also applied these principles to thousands of humans, by teaching large groups, and by working in a close 1-1 setting with elite performers, special operators, top athletes, and the likes.

      “Master” is not a definite state we can attain, it is a path we can follow. One of continuous questioning, deeper understanding and masterful application of knowledge and skill. I am certainly no master, for the more I learn, the more I realise how much there is to know, and how far I still have to go. I have dedicated my life to that process.

      I am a teacher, and I want to share my experience with people that can truly use it. This is not a quick-certificate weekend, or a pre-defined linear course, this is a deep dive into a creative process of self-development as a human, as a coach, as a breather.
