From the reviews

Dropped in as a blue belt for jujitsu during New Years holidays. Though the class was small due to the holidays, the people there were super welcoming to me visiting. It feels like my 2nd home gym. No one there was overly aggressive and I really enjoyed every spar.

★★★★★ — Chin, Jan 2025

Ever since I started training here, I have absolutely fell in love with martial arts than before. The gym has a great community that helps you evolve and makes you feel welcomed! Coaches at Kaizen have years of experience and will take the necessary time to make sure students can grasp and apply techniques with ease.

★★★★★ — Asa, Jan 2025

As a drop-in student from out of town, I was thoroughly impressed by my experience at Kaizen Jiu Jitsu. Everyone was incredibly welcoming and made me feel right at home. The gym itself was spotless, which is a huge plus, and you can tell they take pride in keeping the training area clean and safe.

New to muay thai? Start at Kaizen Jiu-Jitsu Academy

Kaizen Jiu-Jitsu Academy 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 Kaizen Jiu-Jitsu Academy

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. 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.
