You’re taking care of everything: except, sometimes, yourself.
Work, family, and responsibilities come first. Your own health gets whatever time and energy are left.
You can get started. It’s staying consistent that’s hard.
When life is going well, so is your routine. When things get busy, it’s often the first thing to slip.
You’ve tried to figure it out, but there’s too much conflicting advice.
Train more. Eat less. Sleep better. Stress less. You know the advice, you just need to know what actually matters for you.
You’ve tried before, so you’re understandably cautious about trying again.
You don’t need another short-term fix. You need an approach that works with your life, and keeps working when life changes.
Real people Real results.

Founded with a purpose
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.
One.Journey
We look at where you are now. Training history, lifestyle, nutrition, sleep. Your plan starts here.
Together we decide what success looks like. Clear targets, specific timelines, built around your life.
Your training and nutrition plan is built around your goals, your schedule and where you start. Adjusted as you progress.
Regular check-ins and measurements keep your progress visible. Your coach uses the data to keep your plan sharp.
Between sessions, your trainer stays close. Questions answered, adjustments made, accountability kept.

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.
