From the reviews
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.
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.
I really enjoy learning about B.J.J. and Muay Thai at onyx gym. I have been going there for a couple of years practicing Muay Thai and I just started with B.J.J. Zach is not only a great instructor but a really great person as well. He is very patience and professional when it comes to teaching new students.
I've been training at Onyx for 6 months and have nothing but good things to say about my experiences there. Zach is an amazing head jiu jitsu coach (along with Kevin, if you can make the AM classes), and I've made more progress in the past 6 months than I had in my previous 2 years of training.
New to muay thai? Start at Onyx Combat Sports
Onyx Combat Sports comes up as a beginner-friendly gym — noted on their own site. If you've never thrown a punch or a kick, 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 to start — you get in shape by training, not before it, and coaches scale the conditioning to you. Second, you won't be thrown into sparring — reputable gyms build fundamentals (stance, footwork, and the basic strikes of the "art of eight limbs") for weeks before any contact, and sparring stays optional. 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. Most gyms are happy to let you watch or try a class first, so reach out before you commit.
Your first muay thai class at Onyx Combat Sports
Nervous about walking into a muay thai 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 the basics on pads and bags — not fighting. Rest whenever you need to; no one will bat an eye. What to wear: shorts or athletic wear and a t-shirt; you'll train barefoot on the mats. What to bring: water and hand wraps if you have them — many gyms lend gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves, wraps, a mouthguard, and shin guards. Sparring is optional and comes later, 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.
