Your sports nutrition coach

I’ve been playing sport since I was six

I’ve been an athlete since I was six. Not just for fun, but a serious one. Judo, competitive swimming, water polo up to the highest amateur level, aikido (black belt, 3rd dan), marathons and ultramarathons. Almost fifty years on, I still train every day: Brazilian jiu-jitsu (blue belt), strength training and running.

It is that breadth of knowledge that sets me apart as a sports nutrition coach. Water polo, marathons and jiu-jitsu each place different demands on your energy, physical strain and recovery. I know them from the inside, not just from a book. As head coach of men’s and women’s water polo teams – with the women’s team competing at the top division of the national league – I spent five years seeing just how much nutrition and recovery influence performance. My specialism lies in endurance sports and martial arts, but I help athletes from all disciplines.

Training and knowledge

In 2012, I completed the BGN-accredited Sports Nutrition course at the Leidsche Onderwijsinstellingen, after which I worked as a sports nutrition coach for five years. After a deliberate break, I resumed this work in 2024. I keep my knowledge up to date through specialist literature and modules by Prof. Asker Jeukendrup (MySportScience Academy), one of the world’s leading sports nutrition scientists.

Why I developed TWINDO One

I believe that sport enriches your life, at every level and at every age. Good nutrition is what enables you to keep it up. But personalised guidance from a sports nutrition coach isn’t feasible for many recreational and amateur athletes, and one-off advice doesn’t adapt to your training schedule. What remains is a lot of noise: supplement adverts, fads, generic apps and AI responses that know nothing about your sport.

That’s why I created TWINDO One. It’s not just another app from a tech company, but my own approach as a coach, translated into daily advice that adapts to your training sessions and competitions. It’s affordable, personalised and ready to use straight away. From the Check subscription onwards, I’ll be there to guide you as your coach.

Also for sports entrepreneurs

As well as providing sports nutrition advice, I build WordPress websites for independent sports entrepreneurs and sports clubs. Not as a run-of-the-mill web designer, but as someone who understands your world and works with you to figure out what will appeal to your target audience. View web design.
