From the reviews

So I have been training at Claycomb Academy of Martial Arts for a year now and not a day goes by that I’m not grateful for being apart of this dojo! I like that the classes are small enough that you get lots of attention from the Sensei’s and Shihan, the dojo itself is clean, and the fact that we work with pads and…

★★★★★ — Carolyn, Oct 2020

Claycomb Academy of Martial Arts is a true testament of growth. With over 20 years of experience. This is the best place to bring your children to learn real karate. They also have great classes for adults. A spacious clean facility to step into. Also, a place to witness Michael Sugarbomb an amateur kickboxing Fighter.

★★★★★ — Kifflom, Feb 2025

I highly recommend this Dojo. My son has attended for several months now and he is loving it. It’s a very clean facility. The Sensei and his assistants are knowledgeable and are all friendly and caring. My son is learning discipline, respect and honor. It is a family friendly dojo.

★★★★★ — Yvette, Feb 2025

CLAYCOMB Karate Academy has been a great place and still is. I have been coming here for almost a month now, and it is amazing! My 3 boys also attend their classes and I have seen some improvement in social communication and feeling better in their daily lives.

Your first kickboxing class at Claycomb Karate & Kickboxing

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.
