Founded with a purpose
After losing a family member, Glenn, our founder, understood that health cannot wait. He built ONE to be more than a gym. A place where real support meets real people, so you progress in real life.
A smarter way to train
Most fitness offerings focus on one thing. ONE brings everything together.

One community
At ONE, you train alongside people who are serious about their progress, in a space built for real connection. One tribe, working toward the same standard.

Yes. You can pause for up to 4 weeks per calendar year, taken as 2+2 weeks or 4 consecutive weeks, with 4 weeks' notice. For cancellation: cancel at the end of your first 4-week period with no notice. After your second period begins, we ask for 4 weeks' notice. Both are handled in the Trainin app. (Note: pausing doesn't apply to one-off Flex packages.)
Our group classes are our Semi-Private Training (SPT) sessions: small-group, coach-led, and structured around twice-a-week training. Beyond that, we run community events and the occasional challenge or competition, like the ONE Open, but SPT is the core class offering.
Personal training is included in all three PT memberships — Basic (8 sessions), Premium (8 PT + 4 SPT), and Platinum (12 sessions). It's also part of the Semi-Private Premium membership (1 PT session per month) and available as a standalone PT Flex package.
No, you don’t need any experience. We build the confidence, knowledge and strength from the ground up.
Simply by leaving your details. Our Customer Success Team will reach out and set it up. In this call you will talk through your goals, what's motivating you to change, and what's held you back so far.
Semi-Private memberships run from €329 to €399, and Personal Training memberships from €789 to €1,149. Billing is every 4 weeks rather than monthly, with the first payment due before your intake session. Flex packages (one-off) start at €675 for SPT and €1,650 for PT.
No problem, your plan flexes around it. You get 4 weeks of pause per year, and your coach adjusts the remaining weeks so you don't lose progress.
You keep going, if you want to. Most people roll straight into a regular membership once they see what 8 weeks of structure actually does to your health.
Yes, you can, but this month we are offering a free athlete assessment and we've only got 20 spots available. Training works whenever you start, but the sooner you begin, the sooner you’ll start feeling stronger and healthier.
You can expect to feel stronger, move better, have more energy and build a more consistent training routine. You may also feel better in your clothes, leaner, stronger and gain a clearer understanding of what your body needs. Individual results depend on your starting point, goals and consistency.
All our coaches speak English (plus other languages) not everyone speaks Dutch.
