In just six months, I’ve lost weight, built strength, and achieved more than I thought possible. This gym’s professional approach, personalized programs, and supportive environment make it a great choice for anyone serious about their fitness goals.

After losing a family member, I understood that health cannot wait. I built ONE to be more than a gym. A place where real support meets real people. So you progress in real life.
Membership plans starting from only €83 per week.
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.
Book a free consultation 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.
There's no strict minimum, but our standard memberships are best suited to roughly 20–75 years old. We don't recommend targeted, machine-based strength training under the age of 12, bodyweight work is the better approach at that stage. For younger people we run our Stronger Future programme, and for those 65 and over we have our Golden Age class. Both are free, our way of giving back to the community.
Book your visit and see how training, lifestyle and context come together in one system, built around you.
Thanks for reaching out. We will be in touch shortly.
