Whether you are new to training, getting back into it or simply want a change, we make your first steps clear and comfortable.
No. You do not need to be fit to start CrossFit. You come to CrossFit to become fitter, stronger and more energetic.
At CrossFit NulDertien, we adjust every workout to your level. Whether you have not trained in years, want to get back into sport or simply wonder if you can do it: our coaches guide you step by step. All you need to do is take the first step.
You would not learn to swim first and then go to swimming lessons. You go to swimming lessons to learn how to swim. CrossFit works the same way, just with a few more squats.
A free consultation is for you if you first want to talk things through calmly. You meet a coach, discuss your goals and can ask anything you want to know. No workout, no pressure and no obligation. Just a relaxed way to see whether CrossFit NulDertien feels right for you.
A free trial class is for you if you would rather experience what a CrossFit class feels like right away. You join a regular class, of course adjusted to your level. That way, you get to know the atmosphere in the box and during the class. Afterward, you sit down with the coach to talk about your goals, what you want to achieve and how CrossFit NulDertien can help you get there.
Yes. At CrossFit NulDertien, you train at your own level, always with a coach guiding you. Every exercise can be made easier, lighter or calmer. That is exactly why CrossFit is suitable for beginners: you do not need to know everything already, you learn it step by step.
From the outside, CrossFit can sometimes look intense. But once you are in class, you see that everything can be adjusted to every level. You train with all kinds of people: from committed athletes to people who have not trained for thirty years, and everything in between. Everyone is working on their own progress.
During your first class, you will be warmly welcomed by the coach and the rest of the community. You find a spot for your things, fill your water bottle, get changed and then simply join a regular class. Nothing strange, nothing awkward. And there is a good chance the eleven other people in class also found their first session exciting once.
The coach takes you through the class step by step: from the welcome talk at the whiteboard, to the group warm-up, maybe a strength part and then the workout of the day. A lot may come your way, but you are not on your own. The coach explains everything, checks your technique and the people around you help you through it too. Some may have started yesterday, others may have trained here for ten years, but they are all friendly and helpful.
Afterward, you get a high five, grab your things and drop onto the couch sweaty but satisfied. And you will probably think: “Okay, that was actually way more fun than I expected.”
Yes, very well actually. Because every class is fully coached, you do not have to think about what to do or how to train. You walk in, switch your head off for a bit and simply follow the class. Pretty nice when the rest of your day already asks enough from you.
A CrossFit class takes 60 minutes. In that hour, you train your whole body: strength, conditioning, stamina and technique all come together. So you do not need to wander around a gym for hours to get results.
And yes, you will train hard. But it is also genuinely fun. For one hour, you can stop thinking about everything else, laugh with the people in class and still become fitter, stronger and more energetic. One hour for yourself, with maximum results.
