From the reviews

When I walked into here I didn't expect how welcoming it would be. The coach Tengo even on my first day made me feel very welcome and cracks some funny jokes in-between teaching. He is also very glad to help me on the moves because I am a beginner and explained them very politely and well.

★★★★★ — Bobby, May 2026

We’ve had an amazing experience at Mutant MMA! The professors are outstanding — not only are they highly skilled, but they truly care about each student’s growth. In the past year, my son has gained so much more than just jiu jitsu techniques.

New to kickboxing? Start at Mutant Mixed Martial Arts & Kioto Jiu Jitsu

Mutant Mixed Martial Arts & Kioto Jiu Jitsu comes up as a beginner-friendly gym, going by their listing and members’ reviews. If you've never thrown a punch or a kick, that's exactly who a good beginners class is for. A few things worth knowing before your first week. First, you don't need to be fit or coordinated to start — you get in shape by training, not before it, and coaches scale every drill to you. Second, you won't be thrown into hard sparring — reputable gyms build the basics (stance, footwork, and punches and kicks on pads and bags) first, and any contact eases in gradually under a coach's control. Third, all fitness 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 kickboxing class at Mutant Mixed Martial Arts & Kioto Jiu Jitsu

Nervous about walking into a kickboxing 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 — stance, footwork, and punches and kicks on pads or a heavy bag — not hard sparring. Go at your own pace and rest whenever you need to; no one will bat an eye. What to wear: comfortable athletic clothes you can move and sweat in, and supportive trainers. What to bring: water, and hand wraps and gloves if you have them — many gyms lend loaner gloves for a first class, so it's worth asking when you call. As you keep training you'll add your own gloves and wraps (and shin guards once you start sparring). Sparring is optional and eases in gradually, once your basics 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.

Kickboxing is a contact sport. Warm up, pace yourself, 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.
