Why now

Seven years of work, bundled once

1,500+people trained
40+countries
16programs
45+hours of material
A full church of participants after a shared breath session

Over the past seven years I trained more than 1,500 people, from more than 40 countries. In that time we developed over 45 hours of training material and guided sessions: theory, protocols, live recordings and original music.

A successful training company is a wonderful thing. And still, I feel it is time to carry the mission deeper. We are doing that through a foundation, bringing breathwork to the places in society where it is badly needed and barely available, such as healthcare and education.

We are starting that foundation with a clean slate. So we are offering the work of Breathwork Masterclass one last time, complete, at a price that need not stop anyone.

Seven years of refining

What makes these courses different

Breathwork is everywhere by now. What sets it apart is rarely the exercise itself, but how it is explained, guided and framed. These are the six things I spent seven years refining.

FINALLY UNDERSTAND HOW IT ACTUALLY WORKS

No dusty lecture and no vague story. With the whiteboard technique you see in a few minutes what happens in your lungs, your blood and your nervous system. You will be surprised how enjoyable it can be to learn the science of your own body.

PRINCIPLES, NOT TRICKS

Most courses only teach you exercises. Here you learn the core principles underneath. Understand those and you understand almost every breathing exercise you come across, and how to apply it to shape your life for the better.

SESSIONS ON A LIVING RHYTHM

The breathing exercises run along with handpan rhythms played specifically for that exercise. No counting, no thinking about your pace. The rhythm carries you, so you can relax and move toward deep calm.

DEEP JOURNEYS WITH LIVE SOUNDSCAPES

For when you want to go deeper into yourself: longer guided sessions with original, live recorded soundscapes. Unique music, tuned to your session, moving along with the spoken guidance.

SAFETY AND INTEGRITY AS THE FOUNDATION

Breathwork can be intense, and not everything is for everyone. You learn to understand which breathing exercises suit which moment, and how to practice safely without falling into the pitfalls of breathwork, which are too often unknown.

YOU ARE NOT BROKEN

Your body is a remarkable self-balancing mechanism. You learn how your breath influences your state, so you gain a little more say over your feelings and thoughts. No unrealistic promises, and no suggestion that something in you needs repairing.

Kasper van der Meulen

Founder, Breathwork Masterclass

Over the past seven years I trained more than 1,500 people, from more than 40 countries. Before that I spent years testing everything I could find in the world of self-optimization, and worked with the scientists, doctors, yogis, therapists and coaches shaping the modern wave of breathwork.

I shared these principles on large stages, at deep-dive retreats, and one on one with top athletes, elite performers and influential people. Everything that came out of that is in this library.

Frequently asked questions

Any questions left?

How long do I have access?

For life. You pay once and the library stays yours. We keep hosting the content for our users. Should we ever stop, we will give you the chance to download everything so you keep it.

What is your refund policy?

Try it for 14 days. If it does not feel like a match, send an email to hello@breathworkmasterclass.com and you get the full amount back. No forms, no awkward exit interviews.

What language is it in?

Most of it is recorded in both Dutch and English, and you can switch at any time. Each course above states which language you get.

Three parts exist in one language only. The Ademkracht series and the Jacobikerk session are recorded in Dutch only, because they were made live for a Dutch audience. Masterful Coaching Principles is in English only.

How much time does this take per day?

Most sessions run 5 to 15 minutes. Some are longer if you want a deep journey. The idea is that it fits your real life: a coffee break, before a meeting, before sleep.

Will new content be added?

No. This is the complete, finished library. Sixteen programs, over 180 lessons and sessions, and that is exactly what you get.

Why is this the final edition?

Because we are moving our energy to a foundation, bringing breathwork to the places in society where it is badly needed and barely available, such as healthcare and education. We offer this bundle up to and including 31 December 2026.

Is breathwork safe? Can anyone do this?

The exercises are safe when you do them as guided. Consult your doctor first if you are pregnant, have epilepsy or a history of seizures, a heart or vascular condition, severe asthma or COPD, high blood pressure, or a history of severe PTSD or trauma. The course The Breathwork Manifesto, which is included, covers safety in detail.

Wasn't Level 1 the coach training? Why can I simply buy it now?

Level 1 is the foundation: the theory and the exercises, perfectly good to use for yourself. What it does not include is the deeper professional content, the live guidance and the certification. That stays reserved for our trained students, because applying it safely asks for guidance.

I already bought some of these courses separately. What now?

We thought of that. If you bought from us before, you have already had an email about what the end of Breathwork Masterclass means for you and which arrangement applies to you. Did not see that email, or unsure whether you would be buying something twice? Email us at hello@breathworkmasterclass.com. We will look it up and make sure you do not pay twice for the same thing.

What happens after I buy?

Within 15 minutes you get a confirmation email with your access. Log in, pick a session, press play.

I have no time right now, can I start later?

Yes. From the moment you buy, the material waits patiently for you. No expiry date, no complete-by timer.

Can I give this as a gift?

Yes. Send us an email after your purchase and we will send you a gift code, perfect for a birthday, Christmas, or someone who deserves a little more breathing room.

Over 45 hours of breathwork, yours forever.

Seven years of training material, guided sessions, music and lectures, including Level 1. One payment, lifetime access, 14 days risk free.
