★★★★★ — Andrew, Dec 2023

This is the best place to learn grappling in the rockford area. This gym goes above and beyond by bringing out some of the best talent in the business regularly to help it's students and the Rockford jiu-jitsu community in general get better. My daughter has gotten so much better since we started coming to blackflag.

★★★★★ — Trevor, Jun 2024

Exceptional gym with a great environment. This gym is a great choice wether you’re a 285 pound man or 110 pound women, black flag has partners for you who are happy to help you learn and improve. Open mats are the busiest day of the week but also the best time to drop in and meet some new people.

★★★★★ — Joshua, Sep 2023

I can't say enough amazing things about all the coaches at black flag. I'll admit it's a bit intimidating first coming in and not getting in the mats. Sitting on the bench you feel a bit like the non cool kid watching all the cool guys have fun but that doesn't last long everyone is inviting and kind and always joyful.

New to BJJ? Start at Black Flag Jiujitsu

Black Flag Jiujitsu comes up as a beginner-friendly gym — noted on their own site. 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 Jiujitsu

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.
