From the reviews

As I am coming up on a year attending classes and functions at Fluid Jiu-Jitsu, I just wanted to write a quick review of this gym/dojo/family meeting place. Not sure what to call it as it fits many names. I first have found everyone to be very accepting and encouraging no matter where you are on your fitness journey.

★★★★★ — Margaret, Nov 2022

Both my son and I attend classes throughout the week and love it here. Fluid Jiu Jitsu feels like a family, and everyone is very open to taking time to help. Brent is an excellent teacher and can simplify intricate techniques, making both the adult and kids classes fun and interesting.

★★★★★ — Scott, Feb 2018

Can't say enough good about this place. I've only been coming for 4-5 months at this point, but I've felt like I've belonged since day one. Everyone is super welcoming and willing to teach.

★★★★★ — Andrew, Feb 2022

Fluid Jiu Jitsu is a comfortable, highly knowledgeable and fun gym to learn and practice martial arts. From Brenton to Miguel, the staff does a wonderful job educating a wide range of students. No matter if you’re young and just starting, or older and experienced, you’re more than welcome to attend classes at Fluid.

New to BJJ? Start at Fluid Brazilian Jiu Jitsu

Fluid 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 Fluid 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. 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.
