Decode.
It starts with a conversation, not a checklist. Your goals, your history, your schedule, and what you've already tried. Where data adds value, I bring it in. You don't need a folder of test results to get started.
Arcanum
Decode. Optimize. Perform.
One-on-one coaching and consulting for people who take their health and performance seriously. A plan you can follow, and results you can measure.
The Method
Three words on the logo. That's the work.
Optimize.
You get a clear, personal plan for training, nutrition, recovery, and supplementation where it makes sense. It has to fit your life. No templates. Nothing you can't sustain.
Perform.
Then we make it stick. Structured check-ins, a direct line when you have questions, and adjustments as your life and goals evolve. Steady progress, not a crash program.
Each client gets all the attention. That's why the roster stays small.
About
Han
I've spent eight years helping professionals, athletes, and the general population get stronger and more capable, and even longer researching and practicing. A background in hospital and acute pre-hospital care shaped how I work: the person first, symptoms in context, and no advice I can't stand behind.
I take on a limited number of clients so every plan gets built, reviewed, and adjusted by me, not handed off, automated, or recycled.
- Experience 8 years coaching professionals, athletes, and the general population
- Approach What holds up in research and in practice. No fads
- Focus Performance, body composition, sustainable health
- Base The Netherlands. Clients across Europe and worldwide, online
The Resources
Most of what I know, I publish.
The podcast, channel, and newsletter are how I try to give back. I want to teach, prevent harm, and let you judge whether I'd be a good fit as a coach without having to pay for it.
- Podcast The Arcanum Health Podcast — on Spotify Coming soon
- YouTube Deep-dives & explainers — on YouTube
- Instagram Daily notes from the practice — on Instagram
