This record is wrong, and the honest thing is to lead with that. The listing is filed as "Hi Power Gym" at Jana Pawla Woronicza 31 in Warsaw. It isn't a gym. Every single review describes a hi-fi audio shop: loudspeakers, subwoofers, air purifiers, home demo loans.
The website on the listing is superhifi.pl. That settles it.
I'm leaving this page up as a correction rather than a gym write-up, because someone searching this address deserves to know what's actually there before they turn up with a gym bag. The 4.4 rating from 81 reviews is real, but it's a rating of an audio dealer.
What the Reviews Actually Describe
A customer in February 2020 (translated from Polish): "I've visited most of the showrooms in Warsaw, and I must admit that this is definitely one of the best, if not the best. The staff is attentive, listens, and advises. They have a wide selection of equipment. Speakers can be rented and tested at home."
Speakers rented and tested at home. There's no reading of that sentence in which this is a fitness facility.
A customer in December 2021 (translated from Polish): "A while ago, I bought speakers and a subwoofer here. The comprehensive industry knowledge and advice are top-notch. They have a fantastic selection of equipment, and the prices are rock-solid."
A customer in December 2017 (translated from Polish): "When it comes to air purifiers they know their stuff and can answer any and all questions."
A customer in February 2026 (translated from Polish): "Super fast shipping. I called on Thursday around 2-3 PM, paid by bank transfer, and had the speaker on the other side of Poland the next day at 10:00 AM."
A customer in November 2025 (translated from Polish): "I'm impressed by the friendliness, knowledge, and approach to the customer. The shop is friendly enough that I always feel like dropping in when I'm passing by."
Five reviews spanning December 2017 to February 2026. Speakers, subwoofers, air purifiers, shipping. Not one mention of a weight, a treadmill, a class, or a membership.
How Did This Happen?
I don't know, and I'm not going to invent a story. Google Places data gets categorised imperfectly, and a business name containing "Hi Power" landing in a fitness category is the kind of mistake that follows. What I can say is that no reviewer here uses the word gym, and the shop's own website is an audio site.
What This Means For You
If you're looking for a gym near Woronicza in Mokotow, keep looking. This address won't give you one, and I have nothing useful to tell you about the fitness options nearby without making them up.
If you're looking for a hi-fi shop in Warsaw, then the reviews above are genuinely positive and consistent across nearly a decade: knowledgeable staff, home demos on speakers, fast shipping. Open Monday to Friday 10:00 to 19:00, Saturday 10:00 to 14:00, which is retail hours and another tell that this was never a gym.
Jana Pawla Woronicza 31, 02-640 Warszawa. The site is superhifi.pl and the number is +48 600 723 436.
