From the reviews
There's this awesome Muay Thai gym called "Good Boy family" that I've heard amazing things about. They have experienced trainers who are really passionate about Muay Thai and will help you improve your skills.
⭐⭐⭐⭐⭐ If you're looking to train in Muay Thai, this is the place to be! Cosmo Alexander isn't just a coach; he's a mentor who pushes you to your limits and beyond. His expertise is unmatched, and the gym atmosphere is both welcoming and intense.
The team is like a family. 👊🙏 Edit: coming back to this a few months later — I just finished my first Muay Thai tournament. It was one of the greatest experiences of my life. All thanks to our amazing coaches Cosmo, Lari, and Christian. 6 months ago, I wouldn’t have thought I could do the things I’m doing now.
Cosmo and Lari are fantastic trainers for all skill levels at Muay Thai Good Family. They both possess a deep understanding of the sport and are dedicated to helping their students succeed.
New to BJJ? Start at Good Boy Family - Muay Thai, Jiu Jitsu and MMA
Good Boy Family - Muay Thai, Jiu Jitsu and MMA comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never rolled or set foot on a mat, 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 or flexible to start — you get in shape by training, not before it, and coaches scale the intensity to you. Second, you won't be thrown into hard rolling — reputable gyms build fundamentals (positions, escapes, and basic submissions) for weeks, live rolling eases in gradually, and tapping early keeps every roll safe. 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, and leave your ego at the door. Most gyms are happy to let you watch or try a class first, so reach out before you commit.
Your first BJJ class at Good Boy Family - Muay Thai, Jiu Jitsu and MMA
Nervous about walking into a BJJ 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 basic positions and escapes with a partner — not hard sparring. Rest whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot on the mats. What to bring: water and a mouthguard if you have one — many gyms lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi (or a rashguard and shorts for no-gi) and a mouthguard. Live rolling eases in gradually, 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.
