From the reviews
I’ve been going to PHAS3 for a few months now, and I have to say, I'm blown away by the experience. From the moment I walked in the door, I was welcomed with open arms and made to feel like part of the family.
What an amazing organization. If you're looking for a highly organized, clean, friendly environment to train and learn the art of Muay Thai and learn ways to overcome life's challenges then look no further. My 9 year old son has been going here for months and absolutely loves it!
Phas3 is legit. I have been training combat sports since childhood and have been in gyms throughout the Bay Area. The second I walked into Phas3 I knew it was the right gym. Almost every week, I learn a new tool or technique from not only the amazing coaches, but through watching the talented fighters that train here.
PHAS3 has been a very welcoming and fun experience. The coaches and staff are great and the classes are suited for beginner to advanced. I had no martial arts experience when I started in September and was looking for a good workout with some combat training and it’s been more than that!
New to muay thai? Start at PHAS3 Martial Arts
PHAS3 Martial Arts 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 PHAS3 Martial Arts
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.
