From the reviews
I am a former Marine and have been training in various locations from Japan, Ft Lenoardwood, to 29 Palms. I do appreciate what I learn from those gyms but none of them compare to Millennia. I have been training here for a year and they have various skills levels which is nice.
I dropped in for the 7pm class while on business and Millenia was incredibly welcome. The owner was kind, the class was excellent with modern technique, and plenty of high quality rolls to round out the class. The mats and facility were top notch and I couldn't recommend it enough.
Love this gym. I have a 7 and 14 year old that prior to here had no experience with jujitsu,wrestling and kick boxing. My kids are loving all of it. The coaches are amazing and pay attention to detail and technique while teaching,which is really important for safety.
I was on a short term work assignment looking for a gym. I dropped in for a visit and immediately signed up when I left. I ended up staying for close to a year and could not have enjoyed my stay any more due to this gym. World Class Coaches paired with the most amazing training partners.
New to muay thai? Start at Millennia MMA Gym
Millennia MMA Gym 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 Millennia MMA Gym
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.
