From the reviews
Amazing place to train for self defense, fitness and/or competition. The main instructor really is an amazing down to earth teacher. Jiu-Jitsu can be an intimidating form of martial arts to begin learning with its rather immense learning curve.
I stopped into Onyx to train for a week while visiting family in PA, and Zach was very kind and welcoming. There were several times for classes which made it easy to find a time to train that fit into my schedule. The classes were a great workout with good techniques being taught.
Onyx is the best gym I have ever trained in!(even though its been my only one) Zach, Kevin and Kalle are all great instructors but when you're there ask for Odyn. Odyn is by far the best thing about Onyx Combat Sports!
I've been training at Onyx BJJ & Muay Thai for a while now, and I can confidently say it's one of the best gyms I've ever been a part of. Zach and Kevin are incredibly knowledgeable and up to date with the latest trends in Brazilian Jiu-Jitsu, which really shows in the way they structure and instruct their classes.
New to BJJ? Start at Onyx Combat Sports
Onyx Combat Sports 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 Onyx Combat Sports
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.
