Science-backed breathwork & cold exposure to build resilience, energy, and focus.
Master Your Internal State.
The Science of Resilience
Two proven methodologies. One integrated protocol for human performance.
The Cold
The cold is not the enemy; it is a teacher. By voluntarily stepping into the ice, we train the body’s cardiovascular system and the mind’s response to stress.
In our modern world, we are rarely uncomfortable, yet we are chronically stressed. The cold acts as a 'reset button.' It triggers a hormetic stress response that reduces systemic inflammation, balances hormones, and produces a rush of endorphins and dopamine.
We don't do this to suffer. We do this to learn how to find calm within the chaos—a skill that translates directly from the ice bath to the boardroom.
The Breath
Most high-performers are over-breathing, fueling anxiety and limiting physical endurance.
While the Wim Hof Method uses breath to charge the system, the Oxygen Advantage focuses on functional breathing mechanics to optimize it. We use science-backed simulation of high-altitude training to improve your BOLT score (Body Oxygen Level Test).
By increasing your tolerance to CO2, we improve oxygen delivery to the muscles and brain. The result is delayed muscle fatigue for athletes, laser-sharp focus for executives, and better sleep for everyone.
"We don't guess. We test."
The Human Edge Protocol isn't about escaping reality; it is about training your nervous system to handle it.
Whether you are fighting for market share or just fighting for a good night’s sleep, your breath is the remote control for your brain.
Shared Adversity
Resilience is forged together.
Master the Mindset
The challenge is 20% physical, 80% mental.
System Regulation
The remote control for your nervous system.
The Human Behind The Protocol
The Story
I didn't find these methods on a retreat. I found them out of necessity.
For 20 years, I operated in the high-stakes world of software and tech. As a CTO, CEO, and Founder, I thrived on the pressure of high-growth companies. But the cost of 'always-on' leadership is high.
Like many high-performers, I eventually hit a wall. The stress of constant decision-making led to burnout and depression. I realized that while I knew how to build companies, I had forgotten how to maintain the machine that built them: my own nervous system.
I turned to the Wim Hof Method and Oxygen Advantage not as a hobby, but as a lifeline. These protocols helped me regulate my stress, clear the brain fog, and rebuild my mental fortitude.
After my last exit at age 48, I decided to pivot. I’m not just here to guide you through an ice bath; I’m here to teach you the tools I wish I had 10 years ago. Whether you are leading a team, fighting in the ring, or managing a busy household, I help you find your edge.

Executive & Corporate Performance
High-stakes leadership requires more than just intellectual capacity; it requires physiological resilience.
I combine 20 years of C-Suite experience with the Wim Hof Method to build programs for leaders who need to perform under pressure without burning out.
Formats:
* Team Offsites: Break down barriers and build deep trust through shared adversity (ice bath) and breathwork.
* 1-on-1 Coaching: Confidential performance coaching for executives facing high-stress periods or exits.
* "The Boardroom Reset": Practical tools to lower heart rate and sharpen focus before critical negotiations.
Fundamentals & Workshops
You don't need to be an elite athlete to feel the benefits. Whether you are a parent managing a busy household, or just feeling "wired but tired," this is your entry point. Learn the science and safety of the Wim Hof Method and Oxygen Advantage in a controlled environment.
What you will learn:
* How to use breath to instantly reduce anxiety and improve sleep.
* Safe cold exposure techniques to boost your immune system.
* Practical tools to manage daily stress (kids, work, life).
Location: Hosted at Lijf & Visie (Soest) via me or Bridge2Cross.
Sports Performance & Recovery
Recovery is where the gains happen. Using the Oxygen Advantage® functional breathing protocols, we simulate high-altitude training to improve your BOLT score and VO2 max.
Focus Areas:
* Nasal Breathing: Maintain intensity with lower heart rate.
* Lactic Acid Clearing: Breathwork protocols to flush the system post-training.
* Mental Grit: Train your mind to stay calm when your body wants to quit.
Deep Dives & Travel
For those ready to go deep. In partnership with Bridge2Cross, we offer long-format training cycles and travel experiences.
* 10-Week Evolution: A structured program to integrate these habits into your lifestyle permanently.
* Winter Travel: Join us in the mountains for the ultimate cold exposure experience.

Next Workshop
The Official Wim Hof Method Fundamentals Workshop.
Location: Lijf & Visie, Soest | Date: March 7, 2026
Stress is not in your head. It is in your nervous system.
You check your phone, manage the family, hit deadlines, and rush through the day. By the time you sit down, you’re exhausted—but you can’t actually switch off.
We treat stress as a "mental" problem. But biologically, it is a physiological loop. Your body is stuck in survival mode.
To break the loop, you don't need more thinking. You need a biological reset.
During a 4-Hour workshop you will learn how to Reset Your Biology.
This is not about "enduring the cold" or proving how tough you are. It is a science-backed training to manually regulate your Autonomic Nervous System.
What you will learn:
🌬️ Breathwork Mechanics: Learn how to shift your blood chemistry to reduce inflammation and alkalinity in minutes.
🧠 Mindset Training: Practical tools to maintain focus and calm when the pressure is high.
❄️ The Ice Bath: A guided, safe experience to train your vascular system and build mental resilience. Optional, but recommended.
Led by Jan Wiersma.
I am not a guru. I am a former Tech Executive (CTO/CEO) who spent 20 years navigating high-stakes leadership. I know what burnout feels like, and I know how to fix it.
As a Certified Wim Hof Method Instructor, I strip away the "woo-woo" and focus on the mechanics. I bridge the gap between high-performance business and human physiology.
My Promise: Safety is priority #1. You will be guided step-by-step. You will never be forced to do anything you aren't ready for.
