From the reviews
Started kick boxing in November 2025 under Coach Silas. I’ve learned a lot these past few months and am stepping into the ring for my first KB fight this Friday with Silas in my corner
Coach Silaz Diaz is an excellent coach and his classes are all excellent I’ve learned so much in such a small amount of time and he’s a great person overall.
Fortify Fight Club is the best gym experience I have ever had. I had a big trip planned that I knew I wasn't in shape enough for and needed something that could really push me. I was also curious about trying boxing as I had no prior experience.
Coach Silaz is an excellent coach. He taught me very well so far and he’s a great person to be around and he is very disciplined in his martial art. (K1)
New to muay thai? Start at Fortify Fight Club
Fortify Fight Club 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 Fortify Fight Club
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.
