The root cause

It’s not how much you breathe.
It’s how.

Most people breathe too much, too fast and through the mouth – learned, not innate. The good news: a breathing pattern can be retrained, like your posture.

Atemstark combines science, body awareness, and targeted breathing techniques to create measurable change in how you feel, focus, and perform. Whether the goal is stress resilience, athletic endurance, or deeper sleep ‐ the method is practical, evidence-based, and accessible to everyone.

“Health and performance aren’t opposites ‐ they depend on each other.”

What breathing training does

Six ways breathing
changes everything

Each benefit is grounded in respiratory physiology ‐ not wellness trends. These are measurable, reproducible outcomes of functional breathing practice.

Focus & Calm

Activating the parasympathetic nervous system lowers heart rate and blood pressure. Conscious, nasal breathing reduces mental noise and sharpens attention.

Sports & Endurance

Greater stamina and faster recovery through improved CO₂ tolerance and oxygen delivery to muscles. Energy-efficient breathing means more output with less effort.

Improved Metabolism

Enhanced circulation and O₂ delivery to vital organs and muscles. Proper breathing supports cellular energy production and waste removal.

Diaphragm & Posture

Correct breathing strengthens the diaphragm, core, and spine ‐ improving posture and reducing the physical tension that builds with chronic shallow breathing.

Protected Airways

Nasal breathing warms, filters, and humidifies incoming air. Nitric oxide (NO) produced in the nasal sinuses opens airways and improves oxygen uptake.

Immune & Inflammation

Improved oxygenation and CO₂ tolerance support cell regeneration and help regulate inflammation ‐ foundational to long-term health and resilience.

About Atemstark

Science-based.
Human-centred.
Built from experience.

I spent years in high-performance corporate environments ‐ fast-paced, demanding, driven by constant output. I believed success meant pushing harder and resting less. Over time I realised: health and performance aren’t opposites. They depend on each other.

That insight led me to the Oxygen Advantage® method, functional breathing, and founding Atemstark ‐ to share what I found with individuals, teams, and athletes who want the same.

Science-based, but simple

Every technique is grounded in physiology, supported by research, and easy to integrate into daily life.

Awareness & Balance

Breath is the bridge between body and mind ‐ it regulates stress, sharpens focus, and restores calm.

Sustainability & Purpose

We create habits that last ‐ improving wellbeing, resilience, and presence far beyond the training itself.

Questions

Frequently asked
about breathwork

Everything you need to know before getting started with Atemstark. Breathing training in Zurich and online.

What is functional breathing?

Functional breathing supports optimal oxygen delivery, calmness, focus, and performance. It emphasises nasal breathing, diaphragmatic efficiency, and a healthy breathing rate. With simple daily techniques, most people improve energy, sleep, focus, and stress resilience.

How does the Oxygen Advantage® method work?

Oxygen Advantage® combines scientifically proven breathing exercises with practical techniques to improve CO₂ tolerance, oxygen uptake, focus, and respiratory efficiency. It includes light breathing, breath holds, and functional movement drills ‐ tailored to your personal goals.

What results can I expect?

Clients typically experience improved sleep, better stress management, more energy, reduced breathlessness during exercise, fewer nasal obstructions, and increased mental clarity. Results often begin within the first 1-2 weeks of practice.

Who is functional breathing suitable for?

Busy professionals, parents, athletes, people recovering from burnout, or anyone dealing with stress or low energy. Those with dysfunctional patterns ‐ nasal congestion, mouth breathing, chronic shallow breathing ‐ benefit considerably.

Can breathing exercises reduce stress or anxiety?

Yes. Breathing directly influences the autonomic nervous system. Nasal, low, and slow breathing activates the parasympathetic system, reduces adrenaline, and improves emotional regulation. Many clients feel calmer within minutes during sessions.

How do I get started?

For companies and teams, we begin with an exploratory conversation to understand your needs and define a suitable format. Individuals and athletes can explore coaching options after an initial discussion. Just get in touch ‐ no commitment needed.

Testimonials

What clients experience after training

Real feedback from people who train functional breathing ‐ in everyday life, at work and in sport.

Great experience. The best thing about what I learnt is that I can exercise anytime during the day ‐ at work, on the bus or on my way to the shop. No extra training time needed ‐ it is fully integrated into my everyday life now!
Christian39, Entrepreneur
The training changed a lot for me, and for the people around me. I finally breathe efficiently and I notice the difference: more energy, better sleep, more patience… Fascinating!
Maurice43, Footballer
Before the breathing exercises with Michael, I had no idea how strongly conscious breathing can influence the body ‐ that, besides improving oxygen supply, it can also help reduce stress and support the immune system. Michael teaches the exercises competently, patiently and clearly. He creates a professional yet relaxed atmosphere in which you feel at ease right away.
Ricardo42, Director in Banking
The training with Michael helped me strengthen my breathing while running. I no longer get a side stitch and feel generally stronger ‐ with easier breathing, more energy, better sleep, simply good.
