Williams Academy of MMA in Fountain Valley is an excellent place for kids 5+ to build discipline, respect, and confidence. Sensei Corey and the coaches run structured classes that emphasize etiquette, listening, and accountability from day one.
My 6 year old son has been attending the mini class for about 9 months. He has grown and learned so much, and this class is doing wonders for his focus in school! Sensei Corey is SO good with kids. He strikes a great balance of being firm and holding high expectations while also being caring and supportive of the kids.
This is my favorite MMA gym. I am taking the striking classes and coach Larry is one of the best! He has sparred with UFC level fighters in the past and the way he teaches makes it easy and effective to learn. One of the best part of this academy is the people. The instructors and students are awesome.
New to muay thai? Start at Williams Academy of MMA
Williams Academy of MMA 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 Williams Academy of MMA
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.
