I’m James Geercke, founder of Frozen Breath — an Australian Wim Hof Method instructor, breathwork coach, and resilience trainer. I'm an army veteran and endurance athlete who helps people build physical and mental resilience using breathwork, cold exposure, and resilience training.
After navigating my own spinal injury, chronic pain, and mental health challenges following military service, I discovered how powerful tools like breathwork and cold exposure can be for recovery, stress regulation, and performance.
Today I work with athletes, veterans, runners, and everyday people who want to reconnect with their bodies, improve resilience, and breathe through whatever life throws their way — even if that sometimes includes 1°C water.
Everything I offer comes from lived experience and extensive study in breathwork, cold exposure, movement training, and nervous system regulation. My background includes military service, endurance athletics, recovery from spinal injury, chronic pain, and overcoming addiction — experiences that shaped my approach to resilience, recovery, and performance.
The services offered through Frozen Breath are designed to help people recover faster, improve performance, manage stress more effectively, and build a stronger, more adaptable nervous system. Through Wim Hof Method workshops, breathwork coaching, barefoot running training, and personalised resilience coaching, the focus is on practical tools that create real improvements in movement, recovery, focus, and overall wellbeing.
I work with all people, ranging from athletes, veterans, people recovering from injury or surgery, and anyone looking to regulate their nervous system and reconnect with their body. This work is about building resilience, confidence, and long-term wellbeing through practical, sustainable methods.

There are many breathwork and cold exposure coaches, but only a few have learned the Wim Hof Method directly from Wim Hof himself. Through my work alongside Wim, I’ve gained firsthand experience in breathwork training, cold exposure, and resilience practices that have helped people worldwide improve their health, performance, and mental strength.
From sharing ice baths to assisting at large Wim Hof events, I’ve seen how these techniques are delivered at the highest level. This goes far beyond certification — it’s built on real-world mentorship, hands-on experience, and direct involvement in breathwork sessions, ice bath training, and mindset coaching from the Iceman himself.
Our ongoing relationship and conversations have deepened my understanding of not just how to teach the method, but why it works. I bring that knowledge into every session, helping clients safely build stress tolerance, nervous system regulation, and long-term resilience.
When you train with me, you’re not just learning techniques — you’re working with a Wim Hof Method instructor who has learned directly from the source, with a proven approach to improving health, performance, and mental resilience.
For thousands of years, humans have turned to cold for strength, healing, and resilience. From the icy plunges of Nordic cultures to Japanese Misogi rituals, cold exposure has been a cornerstone of ancient wellness practices worldwide. These traditions weren’t just about endurance — they were about unlocking the body’s full potential.
Meeting someone who has profoundly influenced your life is a rare experience. And meeting Wim Hof exceeded every expectation I had of him.
Martial arts isn’t about proving anything or seeking conflict. For me, it’s about movement, awareness, and learning to stay calm under pressure.
Running is one of the most natural movements humans can do. For millions of years, our ancestors ran across forests, plains, and mountains without cushioned soles or supportive shoes. Modern running shoes are a recent invention. While they promise comfort and performance, for many runners, they’ve actually created more problems than they’ve solved.
