From the reviews

The best coaches ever! This is the most respectful business I’ve ever walked into. From the instructors to every student I’ve come across - everyone is polite and respectful. I not only have the privilege of having my son train at Assembly line but I also have the pleasure of training, myself.

★★★★★ — Nicole, Oct 2025

Assembly Line Muay Thai is a hidden gem for anyone looking to learn authentic Muay Thai in a friendly, welcoming environment. Coaches Laban and Gary bring over 20 years of experience and world-class training from the elite Sityodtong Los Angeles gym.

★★★★★ — Mimi, Sep 2025

I’ve been coming here since they opened up, and in that time, I’ve really been able to improve my skills thanks to Coach Laban and Gary. No other gym will offer you this level of one-on-one attention and coaching at a fair price.

★★★★★ — Jack, Jun 2025

Awesome place for people of all levels! Super affordable and everyone is very friendly. Been attending a couple times a week for almost a year and I highly recommend stopping by if you're even remotely interested in learning, training, or just want a good workout.

New to muay thai? Start at Assembly Line Muay Thai gym

Assembly Line Muay Thai gym 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 Assembly Line Muay Thai gym

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.
