From the reviews

I began my martial arts journey at Roots, and it’s been a life-changing experience. I started with Muay Thai, and Coach Jamie’s combination of kindness, patience, and toughness helped me grow, even with no prior experience.

★★★★★ — Kaanthi, Jan 2025

Great team with youth Jiu Jitsu classes, fair pricing and great teacher to student ratio. If you want to enroll your kids in a martial arts class, definitely check out this place!

★★★★★ — Paul, Apr 2020

Many of my old gym buddies switched to Roots, truly a hidden gem in the bay area! Coach Jamie focuses on one theme (i.e. boxing) for a couple weeks, keeps it simple at first and gradually builds the combo. I've seen way more improvement in my technique here than anywhere else, even after just a few sessions.

★★★★★ — M, Aug 2024

Roots has truly become a second home for our family. The coaches are phenomenal—skilled, passionate, and supportive—making it easy to see progress whether you’re a beginner or experienced. What we love most is how inclusive the gym is.

New to muay thai? Start at Roots Kickboxing BJJ

Roots Kickboxing BJJ 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 Roots Kickboxing BJJ

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.
