“They break down techniques clearly, are patient with beginners, and push more advanced students to reach their potential.”

From the reviews
I’ve been to a handful of other training facilities, and I have to say Fenrir is my favorite. I do BJJ as a hobby and for physical activity. As an older female, I can feel uncomfortable in a mostly male dominated space, but I’ve felt at ease here. The coach is approachable and scaffolds the curriculum well.
I was invited to Fenrir Jiu Jitsu by the owner and my good friend Kyle, and I’m really glad I went. The atmosphere was welcoming, and the staff was not only skilled but also super down-to-earth.
Fantastic atmosphere. Highly skilled, friendly, and accomodating, professors. After ten years in the art I learned several new ideas and techniques in just my first class. The kids class professor is to notch and great with kids.
Best place I have ever been to!! I am not really an athletic person but this place has helped me to feel comfortable and supported on my journey in learning jiu jitsu! All of the staff are extremely kind, supportive, and passionate about what they do. I would 100% recommend coming here to learn and train!
New to BJJ? Start at Fenrir Jiu-Jitsu Academy
Fenrir Jiu-Jitsu Academy comes up as a beginner-friendly gym, going by their listing and members’ reviews. 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 Fenrir Jiu-Jitsu Academy
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.
