From the reviews
I had been looking for an activity to put myself in last year and knew I wanted to go back to martial arts. When I contacted and met Professor Jaime and Professor Daniel, I felt so welcomed immediately. Everyone trains hard together, motivates each other, and laughs hard together.
No better place to have your children learn self-defense, self-esteem and get a great workout. Coaches are stellar and teach them discipline and respect! Top Notch!
My 10 yr old son has grown and developed not just in JJS skills here, but in character and specifically leadership. He brings his best self to GB because he is inspired to do so.
Gracie Barra is a good place to learn jujitsu. I have been here since I was 5. I like the schedule and they separate the classes well. The Professors and coaches at Gracie Barra are excellent, as they work on exceeding every kid to the best of their abilities.
New to BJJ? Start at Gracie Barra Diamond Bar-Brazilian Jiu-Jitsu
Gracie Barra Diamond Bar-Brazilian Jiu-Jitsu 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 Gracie Barra Diamond Bar-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.
