From the reviews
I'm coming up on 10 months of training at Fairfax Jiu Jitsu and my only regret is that I hadn't started sooner. Prior to my first class, I was anxious. It can be intimidating trying something new. But that anxiety soon left, because the culture inside Fairfax Jiu Jitsu is amazing.
I came to Fairfax Jiu Jitsu over a year ago looking for some martial arts training, unsure of exactly what form I was looking for. I had studied several forms over the years and was looking for something for the "long haul.
I joined FJJ late January 2017, here i am a year later still at the gym training 4-5 times a week. The thing that makes this gym special is the family atmosphere, within a week i felt as if i was apart of the team and started hanging out with teammates outside the gym.
I have been training Muay Thai here for about 2 years. It is a great place to learn authentic Muay Thai. Our trainer has been going to Thailand for well over a decade to learn this stuff from decorated Thai fighters and trainers. You can learn at your own pace.
New to muay thai? Start at Fairfax Jiu Jitsu Academy
Fairfax Jiu Jitsu Academy 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 Fairfax Jiu Jitsu Academy
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. 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.
