From the reviews

This place is awesome. My 5 year old daughter has been training at Undisputed South for 6 months, and she absolutely loves it. The experience has had a major positive influence on her confidence and development, and she's made some great friends too! The owner and head teacher, Mr.

★★★★★ — Luke, May 2020

Two of my kids have trained at Undisputed South for over a year. Through that time, they have experienced boxing, no Gi, Gi, one-on-one lessons and weekly homeschool classes. They have fought in several Jiu-Jitsu tournaments and have performed exceptionally well.

★★★★★ — Shanna, May 2025

My daughter started jiujitsu classes at Undisputed South in 2020, and the experience has been incredibly positive. With no prior exposure to the sport, she has received excellent coaching from Keith and Matt. On a personal note, I embarked on a health transformation journey with Matt, Kate, and Maren.

★★★★★ — D, Apr 2024

Matt Blank and Chris are awesome! I was fortunate enough to receive a veteran's scholarship to training Jiu-Jitsu for and entire year! I learned so much and was able to connect with likeminded individuals. I never felt pressured or concerned about my safety. The team goes at a steady pace for new students.

New to kickboxing? Start at Undisputed | Green Valley Gym | Jiu Jitsu - Boxing - Kickboxing - Fitness

Undisputed | Green Valley Gym | Jiu Jitsu - Boxing - Kickboxing - Fitness 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 Undisputed | Green Valley Gym | Jiu Jitsu - Boxing - Kickboxing - Fitness

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.
