Learning jiu-jitsu in central and western Warsaw

The most legible door in central Warsaw, and the only room on this instrument that plans for the traveling grappler explicitly: its Polish price list carries an English-titled, euro-priced line — 'JIU JITSU COMPETITION TEAM TRENINGS, 2 weeks €100, 4 weeks €189'. For everyone else the arithmetic is printed too: 59 zł for a single visit, benefits cards accepted with no fees or booking, and six adult BJJ slots a week under Jędrek Loska — a black belt beside a published record (World Games gold, a Ne-waza world title), whose own student now teaches as a 2017 black belt 'pod Jędrkiem Loską', the grantor named in the room's own words. Two things to know: there is no trial class — the 59 zł single entry IS the first visit — and the schedule lives in the operator's images, one hall per image, so confirm the grid at the desk

Why we say it: All from the room's own channel, gorila.pl — six pages plus the operator's own schedule and price-list images, read 2026-08-19; robots 'User-agent: *' / 'Disallow: /wp-admin/', checked not assumed. Address, phone, class grid, price matrix, the euro competition-team product and every belt claim are the operator's own bytes, and the address byte-matches the competition platform's registry. Loska's black belt is club-claimed without a grantor; Polczyk's names its grantor on the same page and is stated as exactly that. The schedule's W and P suffixes are unglossed and carried untranslated; the 2022 news stop is carried as a conflict against the 2025/2026 schedule bytes; capacity is recorded as unfound (§19.4)

Warsaw's clearest first-visit arithmetic and its most distinctive room: a Ukrainian-community fight club in Wola whose site speaks Ukrainian first and names its audience in its own words — 'Тренування для українців'. It is also the only room on this instrument that publishes a trial price at all: 'Trening próbny — 40 zł', paid, beside a 69 zł single session and a 390 zł unlimited month. Adults get the no-gi pair — 'GRAPPLING NO-GI', Tuesday and Thursday 20:00, beginner-marked — under head coach Roman Zinchuk, whose page claims a world jiu-jitsu title and a BJJ brown belt (club-claimed, no grantor named); kids get their own jiu-jitsu coaching. Two cautions from the room's own bytes: no adult class is named jiu-jitsu and no gi program is published, so gi players should ask first — and the trial is paid, not free

Why we say it: All from the room's own channel, aresfightclub.pl, five pages read 2026-08-19, the Polish edition reached via the published ?lang=pl route — no header tricks; robots 'User-agent: *' / 'Allow: /' with only *?lightbox= disallowed, and that class avoided. Trial and price bytes are quoted from both language editions and agree; the address is the operator's own embedded business-location record, byte-matching the competition platform's registry; belt and title claims are the club's own words, attributed as club-claimed with no grantor named (§10.10). The adult-grid-versus-team-page tension is carried as a conflict, unresolved; capacity recorded as unfound (§19.4)
