From the reviews

Both of our kids love going to Modern Jiu Jitsu. As parents of two children, we couldn’t be happier with the vibe and level of professionalism at the gym. Professor Carlos is a tremendous teacher and is really great with the kids. Highly recommend!

I just took my first NoGi class at Modern Jujitsu and it was a great experience. The instructors were friendly, knowledgeable, and made me feel comfortable right away. It was a fun and challenging class, and I learned a lot even as a beginner. I’m looking forward to coming back.

New to BJJ? Start at JIU JITSU MODERN

JIU JITSU MODERN 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 JIU JITSU MODERN

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.
