From the reviews

After nearly 3 years of studying under BKJN Julia and SBN Austin, we decided to try another style of martial arts — so now I can give an honest review as someone who has trained at multiple schools with our children. You will not find a better husband-and-wife team instructing like they do.

★★★★★ — The, Jun 2025

I can’t say enough positive things about Coach Julia and our experience at Infinity Martial Arts! I have 2 kids going there (boy age 7 and a girl age 5). They both love going to class and have bonded with their peers.

★★★★★ — Misha, Jun 2023

Infinity has a great system in place- structured as well as a fun environment. You will find ease in their new student intro process, efficient class time and open communication. My daughter has shown improvement in character which is the reason I enrolled her here.

★★★★★ — Aimee, Sep 2024

Infinity Martial Arts has been an impressive experience for our daughter. Coach Julia has created a family atmosphere by challenging students beyond their comfort zones. She is firm but fair, and sets clear expectations for students to follow.

Your first Karate class at Infinity Martial Arts

Nervous about walking into a Karate dojo for the first time? Almost everyone is, and a good sensei expects beginners to come through the door. Here's what to know. What to expect: a typical first class is a warm-up, then drilling basic stances, blocks, punches, and kicks — not hard sparring. Step to the side whenever you need to; no one will bat an eye. What to wear: athletic wear you can move in (or a gi if you have one); you'll train barefoot. What to bring: water, and a mouthguard if you have one — many dojos lend a loaner gi for a first class, so it's worth asking when you call. As you keep training you'll add your own gi and the belt your dojo awards you. Kumite (sparring) eases in gradually, once your fundamentals are solid. Arrive 10–15 minutes early to sign a waiver and meet the sensei. It gets easier fast — most people feel far more at home by their third class.

Karate is a contact sport. Ease in, train within your limits, listen to your instructors, and if you have any injuries or health concerns, mention them before class and check with a doctor if you're unsure.
