From the reviews

What a great experience and training we've received over at 3d martial arts. My daughter has been with gym for about 3 years now since the age of 11and to see the conference she in her day to day life has great, thanks to coach Brandon and his team and the amazing classmates who have worked and trained along with her.

★★★★★ — Juan, Jun 2025

I’ve tried a lot of different types of “therapy” and this is by far the best self coping mechanism I’ve discovered so far. Before Brandon and the team at 3D Martial Arts303, I had never thrown a punch - let alone wrapped my mind around the strategic mechanics of MMA.

★★★★★ — Emilie, Jun 2025

Heyo everyone! Brandon is truly gifted at what he does! I have really enjoyed learning from his vast experience. He goes at your pace but also pushes you harder when he knows you can do more and be greater. He will break down everything with you and do it with you side by side.

★★★★★ — Morgan, Jun 2025

I highly recommend this gym. These coaches are very highly experienced but do a fantastic job teaching and connecting with my son and the other kids. My son has a great time and looks forward to practices every week, and I have 100% confidence in my son’s abilities to protect himself in unfortunate situations.

New to muay thai? Start at 3D Martial Arts 303

3D Martial Arts 303 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 3D Martial Arts 303

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.

Muay thai is a contact sport. Ease in, listen to your coaches, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
