From the reviews
I always appreciate when I walk into a gym and the first thing I notice is how clean & nice it smells. I had a blast learning with a strong group of ladies. We all got to expand our skills. It was such good energy, and the coaches were great.
I can't say enough great things about TMA Boulder! From the moment you walk in, you’re greeted with a clean, well-maintained space that reflects their high standards of professionalism. The gym is spotless, well-organized, and always has a welcoming atmosphere.
I have been a member of Omni Martial Arts for the last year and I can honestly say that this place is one of a kind. The space held by Greg, Alison and the rest of the coaching staff in unmatched.
I have had a very positive experience with this program and the team is authentically family friendly, and clearly know how to teach. My 10 year old daughter found a community of girls that are as interested in martial arts as she is and this has been an absolute game changer.
New to muay thai? Start at OMNI Martial Arts & Fitness
OMNI Martial Arts & Fitness comes up as a beginner-friendly gym, going by their listing and members’ reviews. 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 OMNI Martial Arts & Fitness
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.
