Our mission

The health of the Netherlands is declining.
And we are doing something about it.

We are becoming heavier, moving less, and experiencing more burnouts than ever. Quality of life is decreasing and healthcare costs are rising unsustainably.

At the same time, there is an abundance of expensive quick fixes, health trends, and budget gyms without guidance. 90% do not achieve sustainable results with them.

That is why we help you achieve your health goals yourself through the COMMIT approach. And to maintain them. For beginners and for pros. For the individual, the group animal, and the entrepreneur. What binds us is the dedication: to ourselves, to positive change, to the willingness to invest.

Own your health

The method

We do not guide you to a machine.
We guide you to a different mindset.

Our approach rests on three principles. Together they form the reason why our members stay; even after a year, even after five years.

Pillar 1

Inner attitude

Your internal starting point determines how you look at yourself and others. It is not about what you do, but about the position from which you do it.
Pillar 2

Taking ownership

You are the sole creator of your physical and mental success. Therefore, you do not train from the hope that something will change, but from the conscious decision to realize it yourself.
Pillar 3

Lasting habit

Our members do not come to use up their energy, they come to build it up and challenge themselves. Fitness becomes an intrinsic part of daily life. Just like brushing your teeth.

This method is woven into everything we do: from coaching to group classes and especially our personal guidance.

The founder

I was 106 kilos. And co-owner of a gym.

My name is Arjan Konincks and I am the proud founder of COMMIT Health Club.

Konincks

It has become my drive to guide others on their own journey to vitality, well-being, and happiness.

Around my fortieth, I was successful as an entrepreneur. Together with my wife Jolanda, we had built up two Albert Heijn stores and some real estate. On paper, things were going well. Physically, it was less so: I had slowly grown to about 106 kilos, far too heavy for my height and build. I did not feel comfortable in my own skin.

When Jolanda started managing a gym, the realization hit: as a co-owner, I could no longer stand outside my own health. That one thought: “I am now a gym owner,” changed everything. I started working on my own fitness. It was a challenging journey, but somewhere during that journey, I became what I now call: committed. Determined.

A few years later, I came into contact with Straight Line Leadership and their way of coaching. I discovered that where you come from is the foundation for where you are going. That change is always in your own hands. Not just understanding it, but truly living it. If you grasp that, it gives you strength, space, and peace. And I wish that for everyone.

It has become my drive to guide others on their own journey to vitality, well-being, and happiness. I hope you feel at home at COMMIT. And that we may help you realize your own transformation. But one thing remains: you have to do it yourself.

Our core values

Five values that guide everything we do.

Internally and externally. In how we work with each other and in how we guide you.

Customer-oriented

Our members are central. Always. We listen actively, stay informed about what is happening, and exceed expectations where we can.

Ownership

We set challenging goals together and take responsibility for demonstrable results. For our members, for each other, for ourselves.

Energy

Success and fun go hand in hand. We work in a positive environment, celebrate successes together, and keep it human.

Involved

We form a close-knit community. Open communication, respect, and genuine attention: both within the team and towards the members.

Growth-oriented

The journey counts just as much as the goal. We embrace learning and develop ourselves continuously, personally and professionally.

The team

The faces behind COMMIT.

COMMIT works with a close-knit team of coaches, trainers, and specialists. With the right certifications, education, and a strong drive, our trainers help you build a healthier life. These are the people you will get to know.
