From the reviews

I waited a few weeks before writing this review to give a comprehensive picture of this training facility and its teaching style. Having attended several classes now, here's my insight. But before I share that, let me give you some context about my own abilities.

★★★★★ — Josh, Jul 2024

I live in Santa Cruz but visit the place periodically, and it's always a great experience, so figured why not write a few good words. The facility is immaculately clean and the standard of keeping it clean is very high. Several cleanings daily, weekly deep cleaning and more.

★★★★★ — Victor, Oct 2025

An awesome place, especially for women! I was so scared to try Brazilian Jiu Jitsu, but the instructors and students at Kuleana always make me feel safe and encouraged. This is definitely a special community. Instruction feels personal — instructors make a point to know your name and ask for feedback.

★★★★★ — Elizabeth, Nov 2024

Have been training here many months now. Everyone is super welcoming and fun. Darren is a great instructor and always takes the time to not only explain the moves to you but also feel comfortable in the class. All the teammates are super nice too. Also there's always free candy.

★★★★★ — Wesley, Jul 2023

New to muay thai? Start at Kuleana Jiu-Jitsu

Kuleana Jiu-Jitsu 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 Kuleana Jiu-Jitsu

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.
