My bestseller!

A part of my life in story form with a fictional character who teaches me to do better, to be better, think more precisely, and be prepared for life. Why?
 

 

 
 
For a long time, I had the idea to build a psychological structure that made it easy for me to oversee the intricate systems and processes of the psyche.
 
 
 
Writing it down in story form without making it dull.

 

 

 

 

 

 

 

 

Hopefully, it will inspire you to take the next step in life. To own your progress and your choices.
 
To be yourself, even in situations where your upbringing tells you to comply or conform. That is my hope for you!

Cutting through

Information is useful if you can pair it up with prior knowledge or experience. Let me help you by providing you with the information you need. Which can differ from what you think you need.

Proactive motivation

Before you get stuck in moving forward, we are there to prevent that from happening.

You have been on your own for too long. You need someone you can trust and who has your back when your bias kicks in or when your energy level takes a nose dive. You can't always go about it 100%, but you don't need to have long low lows. 

Result

In the end, all that matters is the results.

It gives you the experience to build on.

We ensure that the results lie close or are exactly on target to what you want them to be.

I got to know Christiaan many years ago when he had just started 'Sport Naturel.'

 

For me, at that time, it was fun; it was a small group of nice people. I wanted to improve my overall condition outside of the 'standard' gym setting. Working in nature and with nature to (re)learn natural skills, strength, confidence, condition, balance, and a bit of self-defense is such a diverse and complete offering there is no need to look anywhere else.

 

Christiaan is extremely knowledgeable, approachable, and curious in and outside his work area. Besides that, he is just a great person. He can push you to a point/limit you might not be comfortable with at first, but he always has experience and knowledge backing him up. If you get an opportunity to work with him, take it; it might be your best decision so far.

 

After he moved to the States, I started looking for a replacement program/training in the Netherlands. I haven't found anything so complete or satisfying as his Sport Naturel program.

 

-Marc Wijma- 

When first started joining Christiaan's lessons, I was near my worst physically.

I had long neglected any sort of self-maintenance to keep myself fit.

 

In my first 'class' I joined, I was able to follow half the training before being exhausted to the point of being unable to continue.

 

I kept at it, with encouragement from Christiaan. Christiaan can uniquely create an environment in which working out is fun and effective, to the point that it is an activity I look forward to every week.

 

Christiaan targets muscle groups that go unused in everyday life to give the body the benefit of overall health while keeping things fresh and enjoyable.

I'm immensely looking forward to being a part of the next step.

 

-Ian Bruner-

I was introduced to Sport Naturel in 2016.

 

I took personal training first, and that gave me a basic physical baseline where I felt confident to do group lessons.

 

During my first group lesson, I felt well-prepared. I now look forward to every group lesson.

I grew mentally, physically, and emotionally because of the lessons that prepared me well to step out of my comfort zone and to become a better version of myself.

 

-Kelsey-

Throughout my life, I've struggled with weight control and sticking with exercising and healthy diet habits. I have had experiences with several types of physical trainers.

 

Christiaan has a very unique and sustainable approach that encourages long-term commitment. He is fun, non-repetitive and encouraging while challenging your limits physically and mentally further than you ever thought possible. Christiaan is not just a trainer; he is also an excellent model and mentor for living life with a healthy mind and body.
