From the reviews

Sensei Charlie is an amazing instructor. He impresses me with his expertise in fighting, as well as his stories of his journey to a black belt. This is a great place to train. You will love it. It is like a family here and you are made to feel welcome.

★★★★★ — Mark, Jun 2019

I've been training for three years and can say it's a life changing experience. I initially signed up hoping to get somewhat fit after college but slowly fell in love with the training, changing not only my lifestyle but also motivating me to be a better person.

★★★★★ — Amrita, Nov 2018

Kenpō Combat academy is very clean and inviting. There is more then ample seating for us parents/Grandparents. Sensei Charlie has a friendly, funny and patient personality and is very good with kids. My Granddaughter Aubree loves it and looks forward to her classes.

★★★★★ — Nanakim66, Feb 2022

Love the training and the instruction is taught very well for all classes. My family and I will be here for a very long time!

Your first kickboxing class at KCA Jiu Jitsu & Muay Thai

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.
