Martin's Fitness Club

Looking for a personal trainer, bodystyling, Technogym cardio equipment, a sunbed or courses in spinning, yoga, pilates, ...? You’ll find all of these in our fitness club.

A serene oasis dedicated to your well-being

Given the current situation, we are obliged to temporarily close Martin'Spa as well as the swimming pool area until April 25, 2021 inclusive. Despite the consequences that this decision generates, we are convinced that it is the best one to take for the good of all.

Pending new measures dictated by the Belgian Government in the context of Covid 19, the Martin's Fitness Clubs are exceptionally closed for an indefinite period.
We are already looking forward to welcoming you as soon as our spaces reopen!
