In most gyms, you’re surrounded by dozens of people who are all doing something different. At The Set, it’s different. Group sessions have a maximum of four participants, which means the coach always sees what you’re doing, how you’re moving, and where you need guidance. That’s not just a marketing promise—it’s simply the model on which the entire gym operates.
Behind The Set is Kenan Jasarevic, a health and performance coach who has been guiding people for years at the intersection of physical strength and mental resilience. He opened the gym in September 2025 on Karperstraat in Oud-Zuid, a neighborhood that suits him: quiet, well-kept, with a clientele that’s serious about what it wants. Jasarevic serves as head coach himself and is very hands-on. You can tell that in his approach.
The space itself is stylish without being over the top. Good equipment, no unnecessary clutter, no screens displaying scoreboards or loud music drowning out everything else. The interior conveys what The Set aims to be: a place you go to work, not to impress. Jasarevic himself calls it a ’third space’—a space between work and home, where you can clear your head and strengthen your body. That sounds almost too neat, but the concept is spot on: small, personal, and well-organized.
Group sessions are limited to a maximum of four participants, which means the coach can always see what you're doing, how you're moving, and where you need guidance.
Karperstraat is located in the quiet part of Oud-Zuid, not far from Vondelpark and Cornelis Schuytstraat. It’s a low-key street, which suits The Set perfectly. Here, there’s no storefront filled with little flags and promotional signs—just a place that does what it’s supposed to do. For anyone who’s been looking for a while for something different from the standard gym—a place where the guidance is truly personalized and the groups are small enough to actually learn from—this is the kind of spot you’ll want to keep in mind.
