It's a great CF box where it's warm even during the winter! Friendly atmosphere, good WODs Magda Kuczbajska is my all time favourite trainer ❤️

Hands down the best CrossFit gym not just in Poland but also in Europe. I have been to many EU countries and nowhere you get best available CrossFit gym space, equipment, expert coaches, an expert Physiotherapist onsite, and an awesome sauna just around the corner from the gym. The place is full of people from across the world, always has great atmosphere and the Polish hospitality is in full display. This is now my default gym every time I do Hyrox races in Europe. Love and respect from USA keep up the great work guys:)

This is the most central CrossFit gym in Warsaw. The staff are very friendly, your 1st class/drop in is free, and the vibe is good. You need a padlock for the lockers (they can lend you one). There are 2 rooms, one main hall for classes with room at the back for drop ins, and a smaller room at the front for PT sessions and drop ins. The gym is on the 5th floor of a commercial building so you cannot drop barbells, you must use the crash pads. It gets humid in summer so bring a water bottle. I didn't use the shower facilities but there were 5 or so stalls in the men's changing room, and plenty of lockers. If you are in Central Warsaw, this is your best CrossFit option. Classes are taught by instructors using both Polish and English. Give it a try and share your experience.

Best CrossFit box in Warsaw! 💪 The coaches and community are super warm and welcoming - they even switched to English during class, which I really appreciated. What I love about CrossFit is that no matter where you are in the world, it always feels the same - the WODs, the cues, and the energy. Minus one star only because it's on the 5th floor, so dropping weights isn't easy (I'm not used to crash pads 😅), but it's manageable. Huge thanks to Coach Nina, Coach Tomasz, Coach Michał, and my boxmates - loved every session! 🙌
