of the adventures and vibes of the 5-day event

explore – apply – innovate – evolve

After graduating our online Level 1 “Breathwork Biohacker” program, it’s time to get hands-on and develop the skills and tools of real-life mastery.

You will learn to do breathing assessments,  apply breathing physiology to specified goals, tailor-make breathing protocols for individuals, wilfully regulate states of consciousness and guide people through emotional release and personal healing. In the process you will gather a toolbox for effective coaching in the breathwork, health and fitness market.

This 5-day live Breathwork Masterclass is a place to deeply and openly apply, learn, share and experiment. With a small group of like minded practitioners, we will create the safest possible space to work at the edges of our comfort zone and grow on a personal and professional level.

This is not a pre-defined linear course where you sit down to go through a standardised set of exercises and experiences. Mastery is not theoretical or conceptual, it is practical, experiential and intuitive. Level 2 is an educational symphony that is co-created by the different bodies, minds and styles of the group.


This full-immersion retreat will give you hands-on experience in:


– Dissecting real animal lung and heart tissue –
– Practicing and explaining many different breathing techniques –
– Innovating your own personalized breathing techniques for specific outcomes –
– Guiding Breakthrough Experiences for emotional release and healing trauma –
– Assessing and improving clients’ breathing quality in just one session –
– Doing bodywork on self and others for better breathing quality –
– Using Psylocybin Microdosing for your personal growth –
– Healing, sharing and connecting in a safe space – 

Educational tools include:


Assessment on self and others


Deep breathwork sessions guided with live music


Guided meditations to physically store memories


Sharing circles to go beyond the cognitive layer


Hands-on biology lab class with microscopes and scalpels


Fluid note-taking on a collective mindmap


Guiding each other through personalised breathwork


Dissecting real animal tissue (lungs, heart, diaphragm)


Undergoing and practicing bodywork and tissue massage


Strategic use of psilocybin microdosing and nootropic supplements (optional)


The breathing assessment is a deep coaching session to help determine the default setting of the clients’ nervous system, and what is needed to restore breathing function. You’ll learn how to tie in breathing behaviour with other life behaviour and lifestyle factors like sleep, digestion, mental calm, stress behaviour and fight/flight strategies. With enough practice you’ll be able to know a lot about a person by watching them breathe for just one minute, and be able take them to the next level in their performance.

This part includes:

  • Determining breathing deficiencies in clients
  • “Reading” the nervous system through breathing functions
  • Making a “nervous system map” with clients to determine “low hanging fruit”
  • Bodywork interventions to improve breathing mechanics
  • Restoring regenerative nervous system functions through breathing
  • Breathing interventions for therapeutic purposes / emotional states
  • Helping clients implement breathing interventions in daily lifestyle
  • How to tailor make breathing protocols for individuals
  • Goal-based breathing interventions for focus, social engagement, energy, sleep, digestion, sports recovery, performance, productivity


We’ll look at the key elements that trigger altered states and especially the states that allow for breakthrough insights and emotional processing. You’ll learn how to trigger someone into a coachable state, determine their limiting patterns and help them effectively process what has been triggered and released.

This part includes:

  • Understanding emotional / physical releases
  • Helping people breathe through mental blockages and shift their awareness
  • Using mental releasing and emotional processing techniques to work with what comes up in a breathing session
  • Creating a safe “set and setting” for deep inner work
  • Using chanting styles and movement triggers to go deeper
  • Accompanying and amplifying breathwork with music
  • Understanding why psychedelic / transcendent experiences may occur and how we may facilitate these experiences safely.

Take their word for it – they know what they are talking about

The Breathwork Masterclass was an amazing experience. Knowledge bombs all over the place, combined with a great diversity of breathing sessions. If you think you know a lot about breathing, think again! Plus getting a 3D experience with actual lungs makes it so much more understandable. If I would get the chance, I’d do the entire masterclass again!

I was searching for a unique experience, and I was not disappointed. Kasper gave us Homework to get well prepared and come with a knowledge base that allowed the group to move forward faster. What I liked a lot is that, every student was already very high level, and we could really learn from each other. The theory was always followed by practical session that helped us to really feel by ourself the principles. Always very interactive. Kasper has a really nice way of teaching that goes with the flow. The long group breathing sessions led by the rhythm of the hang pan were unforgetable. The students from around te world created solid bounds and we keep on sharing ideas through technology and follow up calls. The MLAB facilty and family is amazing , and the Dutch culture is one of my favorite. plus, you can sharpen your mind with plant medicine legally. One of my best learning experience so far.

My experience at the Breathwork Masterclass was extraordinary. I have truly deepened my understanding of the mechanics of breathing and how we can influence our bodies by becoming more aware of our own breathing. I recommend this course to anyone who are curious about the science of breathing and want to experience their own breath as their most accessible tool.

The Masterclass is a deep dive into breathwork and biohacking. It provides a new perspective on human health and performance and shows how breathwork can positively and easily impact the two. Kasper is a master teacher and knows perfectly how to blend theory and practice with passion. Definitely a breakthrough for any one who is interested in breathwork mastery.

Kasper’s masterclass is a short cut to the essence of breathing. Combining theoretical science and practical self experiment, you’ll understand (and feel) the principles behind every breathing technique. If you’re like me and have been looking everywhere, no need to search any longer, do yourself a favor and dive directly to the core. You’ll get the most useful and in-depth content on the subject. On top of that Kasper is a highly skilled teacher and a sensible human being worth knowing. Warmly recommended!

From a full download of principles, theory, and science to the hands-on experiential aspects within the group dynamic and beyond, there isn’t anything this masterclass is missing. Kasper pours on the breathwork knowledge, then integrates it through actual practices and even takes it a step further by taking it into the lab to see it all in action with a full dissection of the lungs, heart, and more. Name another course where you get to do that? I don’t think there is one. In addition, Kasper creates a learning environment that is so fun and opens up deep levels of connection, sharing, and group intimacy that cannot be forced yet comes so naturally.

The Breathwork Masterclass has been transformative in many ways, both on a physical, emotional, mental as well as a spiritual level. Yes we learned, yes we experienced, but it was so much more than ‘just a masterclass’. It was a journey, a profound upgrade of both my breathing & body knowledge, as well as an upgrade of life in general. It has left me with many new insights, thoughts, feelings, perspectives and inspiration. Kasper is a great teacher, filled with amazingly valuable knowledge and lots of silly jokes, he’s a walking encyclopedia as it comes to the breath, the nervous system and optimizing your human experience in this world.

No words can describe my experience of this week. No methods but real explanation. Highly recommended! ❤️

What I’ve learned most in this masterclass is that there is alway so much more to discover about breathing. But the best way is to dive in, experience and practice for yourself. Exactly what this masterclass is all about.
