How to choose a jiu-jitsu gym: the open-mat test

The open-mat post buried the most useful sentence I have written about choosing a gym, so it gets its own post: a gym's open mat will tell you more in an hour than its website will tell you in a year. Websites are where gyms describe themselves. Saturday is where they are themselves. If you are choosing where to start jiu-jitsu, choose by Saturday.

Here is the whole method, which is mostly a watching exercise plus one email.

Before you visit

Make the shortlist on boring criteria, because the glamorous ones mislead. Distance beats lineage: the etiquette of attendance is that you actually attend, and the gym twenty minutes closer wins more Tuesdays than the famous one across town. Schedule beats curriculum: a perfect program at hours you cannot make is a poster. Send the drop-in post's six-word email and ask one extra question, whether you can watch an open mat or take a trial class. Almost every gym says yes to both. A gym that says no to both has answered a different question, loudly.

What to watch for in the room

Five quiet things, none of which is the trophy case:

Who rolls with the newest person, and how. If upper belts take rounds with the obvious beginner and the beginner is breathing fine afterward, you are watching the culture the etiquette post promised exists. If beginners only roll each other in a corner, keep looking.

Whether anyone is teaching when nobody assigned them to. The open-mat post called Saturday the gym being itself; generosity you see when nothing requires it is the genuine article.

How injuries are treated. Listen for how people talk about the missing: a room that says "resting his knee, back next week" thinks in streaks, the injury-habits post's whole religion. A room that jokes about toughing it out is telling you your future.

The warm-up. Veterans who skip it exist everywhere, but a class where nobody shrimps before sparring is a class that has decided falling-safely is your problem.

And the floor itself. The gi-washing post's skin math applies to buildings: mats get mopped, rashguards are normal, and the bathroom is not an afterthought. Clean rooms keep their people healthy and their standards visible.

The trial class, and the only question that matters

Take the trial. You are not evaluating whether jiu-jitsu is hard (it is, everywhere) or whether you got smashed (you did, anywhere). You are evaluating one thing: do you already want to come back? Not whether you should, whether you want to. The attendance thesis this site keeps repeating cuts both ways; the gym that makes you want to return is worth two that merely impress you.

Contracts deserve one sober sentence: read what you sign, ask what leaving costs, and treat a gym that cannot answer plainly the way you would treat anyone who cannot answer plainly.

What I actually did

For the record, I chose mine in exactly this order: shortlist by distance, one email, one Saturday against the wall, one trial class, one easy yes. The trophy case never came up. The guy who showed a visitor where the bathroom was did, and three months later he is still the reason I knew the room was right. Gyms are rooms full of people who chose each other. Watch the choosing, then join it.
