From the reviews

This studio has everything you need for self defense! Great for young kids and adults! It has a gym (free weights and mechanical), boxing ring, and Jiu Jitsu studio. I have four of my children training and myself under Mr. Rommel Dunbar, who has years of experience/knowledge in Jiu Jitsu and boxing.

★★★★★ — Creative, Jul 2018

I try schools at riverside and Moreno Valley for BJJ, but this my experience on Mr.Dunbar gym, when I come in on to watch Mr.Dunbar teenagers class i knottiest it was very clean and well form they all greeted the professor with a bow and they all started doing warmup and drills after that there was some intense…

★★★★★ — Rudy, Nov 2022

I have been in this gym/the jiu jitsu program for a year now and I do not regret going!!! I have had a really awesome experience hear. This gym has really motivated me and built up my confidence. I am so grateful for Mr. Dunbar the professor here. He is very motivating and I have learned a lot in the jiu jitsu program.

★★★★★ — Earth, Nov 2022

My sons have been attending jiu-jitsu classes here for two years now, and I can't imagine a better instructor than Professor Dunbar. The way he gives these kids 100% of his time and attention is remarkable.

New to BJJ? Start at United Brazilian Jiu-Jitsu

United 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 United 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.
