"I've been training with Only4Coaching for some time now, and I can honestly say it's been an amazing experience. The atmosphere is great, the facilities are excellent, and I couldn't ask for a better setup. Highly recommend!"

Stijn. V.
"This is the first training I've managed to keep going to for longer than a few months. The facilities are great, and due to the fact that training is in groups of maximum 4 people, the trainers can always change up your training to accommodate for your level and/or previous injuries."

— FAQ
QUESTIONS,
ANSWERED.
-
No. The first session is an assessment — we meet your body where it is and build from there. Most clients arrive having not trained in 5–15 years. The plan is built around that, not despite it.
-
One to five people per coach, programming written for you specifically, and a coach watching every set. It's the closest you can get to 1-to-1 without the 1-to-1 price.
-
Two coached sessions a week is the floor. 60 minutes each. That's roughly 4% of your week — hence the name.
-
Yes. Programs are built around travel weeks. Hotel-gym variants, deload windows, and online check-ins keep the trajectory intact when you're away.
-
Rarely — 1-to-1 is available for clients who have specific rehabilitation needs. Most clients choose semi-private for the value and the room energy.
-
Discovery visits are free. The 6 Week Transformation is €475. Ongoing coaching starts at €350/month. Full breakdown on the Programs page or at your discovery visit.
Still uncertain? The discovery visit is free, and we treat it as a real consultation — not a sales call.
