From the reviews

Nico is the best instructor! My kids love him and respect him. My son was 5 when he started, and had difficulty listening, focusing, and following instructions, especially in school.

★★★★★ — Amanda, Oct 2023

Sensei Nico is amazing! He is great with all age groups and personalities. The flexibility in times and days worked with our schedules. We got to experience classes at the dojo and virtually when everything was shut down. Even doing belt tests virtually! Our son gained so much in being a part of this studio.

★★★★★ — Juliana, Jul 2020

Sensei Nico is amazing. He helps students understand on “their level” since everyone learns different. The dojo just got another Sensei also, Sensei Oscar is amazing and slows down the forms to help everyone learn/remember what part comes next in the form. The dojo definitely treats everyone like a welcome family.

★★★★★ — Brittney, Jul 2022

Sensei Nico is amazing to work with. He has exceeded my goals and expectations for my son's training and my own. Highly recommend. As soon as my training is done, I can go after those pesky ninjas who kidnapped my girlfriend.

★★★★★ — Devon, Jan 2024

Your first Karate class at Z-Ultimate Self Defense Studios

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.
