Fitness club and gym in Mladá Boleslav

MarvelGym is a modern industrial fitness club in Mladá Boleslav. It was built in an old factory and combines raw brickwork and exposed structures with premium equipment you won't find anywhere else in the region. Whether you're in a gym for the first time or preparing for a competition, you'll find the space and the people to move you forward.

You can train at three branches across Mladá Boleslav – Glücknerova hala, Staroměstské náměstí and Sportovní hala. Each has its own character: from spacious halls with top-class machines, through quiet zones for maximum focus, to a cardio zone under neon lights. One membership, three different spaces.

Besides open gym access we offer group classes – circuit training, functional training and other formats led by our instructors. You book them online or in the mobile app, pay with credits and your spot is guaranteed. If the time doesn't suit you, you can join as a substitute and the system moves you up as soon as a spot opens.

Want results faster? Our team of personal trainers will put together a training plan tailored to you – whether you're working on weight loss, muscle gain, rehabilitation after an injury, or just want to learn the right technique. You'll find all trainers' profiles and specialisations on the Trainers page.

A new building, clean changing rooms, a designer washroom and air recovery ventilation go without saying. Come and see for yourself – your first visit will tell you more than any text.
