They have a well built and clean facility you can tell they poured their passion into. The mats are really good quality and fun to roll on.

Been going here for over a year now and this place is great. The people, atmosphere and instruction is all top notch. We also have a decent amount of females that train which is nice! Training jiujitsu has not only helped me gain confidence but friends as well.

★★★★★ — Kerra, Oct 2023

Drive from North OKC and it’s well worth the extra drive time. My son and I love the gym and coaches. I’ve trained a few places but this gym is hands down the best!

★★★★★ — Jared, Aug 2023

Could not be happier. A place for me and my family to grow while learning a skill set that will actually be useful in life, and it comes with so much more… brother/sisterhood for all members no matter the age, someone else to help teach my kids discipline and respect (which is much needed in todays world) and of…

New to BJJ? Start at Black Flag Brazilian Jiu-Jitsu

Black Flag Brazilian Jiu-Jitsu comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never rolled or set foot on a mat, that's exactly who a good beginners program is for. A few things worth knowing before your first week. First, you don't need to be fit or flexible to start — you get in shape by training, not before it, and coaches scale the intensity to you. Second, you won't be thrown into hard rolling — reputable gyms build fundamentals (positions, escapes, and basic submissions) for weeks, live rolling eases in gradually, and tapping early keeps every roll safe. Third, all levels really are welcome — ask about a dedicated beginners or fundamentals class time so your first session is alongside others who are also starting out, and leave your ego at the door. Most gyms are happy to let you watch or try a class first, so reach out before you commit.

Your first BJJ class at Black Flag Brazilian Jiu-Jitsu

Nervous about walking into a BJJ gym for the first time? Almost everyone is, and good coaches expect beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling basic positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the coach. It gets easier fast — most people feel far more at home by their third class.

BJJ is a contact sport. Ease in, tap early and often, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
