Awesome gym. Great welcoming environment. The karate and the Brazilian Jiujitsu instruction is very high level. Some super tough rolls in grappling. An excellent summer program for the kids when they are off from school. I have visited multiple times and it was always an amazing experience.

Preparing your child for Success In Life

At Johnny Karate, teens build more than physical skills, they build the mindset for success. Our program helps students develop confidence, sharper focus, and the self-discipline needed to excel both on the mat and in the classroom. Through structured training and consistent goal-setting, teens learn how to manage their time, stay motivated, and push through challenges. The result? Greater self-belief, improved concentration, and habits that often lead to better performance at school and in everyday life. Here, students don’t just train, they grow into more confident, focused, and responsible young leaders.

frequently asked questions

Most frequent questions and answers about our Martial Arts Programs

Will My Child Become A Bully?

We find that our students become more confident to stand up to bullies and have more humility and kindness to others through their martial arts lessons.

Do Parents Need To Stay?

We don’t require parents to stay during classes. However, we do find that parents who get involved with their kids martial arts lessons, truly build a solid connection as they see their child grow in confidence and skill as they progress through their belt ranks. And building strong family units is important to us at Johnny Karate NYC for our Brooklyn community.

What Do I Need To Bring To My First Lesson?

Make sure you wear comfortable clothes you can do sport in! Not really suitable to practice kicks in a skirt.😳

Be sure to bring a water bottle to your martial arts classes. You will find Johnny Karate NYC in Brooklyn have martial arts classes for kids and adults that are a great workout and lots of fun! Most students are grinning from ear to ear by the end of the class. I am sure you will be too!

My Child Has ADHD, Will Martial Arts Help?

Yes! One of the great things about martial arts classes, is that it’s an individual sport, done in a group environment. We find all our students improve in their focus, self control, discipline and social skills. But the best part is…. They don’t even realise that is what our highly trained Kids Martial Arts Instructors are actually doing. They just think they are having fun!

The best way to find out for yourself, is to take advantage of our limited time offer. You’ll find our team so helpful and dedicated to helping your child become the best version of themselves. Book in now! You will be glad you did!

Are Parents Allowed to Watch?

We encourage parents to watch their children in their kids martial arts lessons. We love parents getting involved! And so do their kids. Even better… join into some of our martial arts classes for adults. Your kids will love that you have something in common. It will build a strong family bond!

Additionally, if you wanted some ‘me-time’? Simply drop them off, and go grab a coffee. They will greet you with a huge smile when you return, because they had SO much fun!

My Child Is Not Athletic, Will They Feel Left Out?

Not at all. You will find that martial arts classes are the PERFECT sport for kids who are not good at sport. Kids martial arts classes really are an individual after school activity, that they do in a group.

The journey from white belt to black belt is different for each student. But what is the same…. They improve co-ordination, balance, motor skills, focus and discipline. Plus, they makes lots of great friends!

Our Instructors are highly skilled in teaching martial arts for kids. Really… It’s their PASSION!

My Child Is Addicted To Computer Games, Will This Be Suitable?

This is probably the BEST kids activity for children who enjoy screen time.

Getting kids active, without them realizing they are learning, is our skill. Kicking and punching pads is such a great stress relief, that kids feel better when they leave our studio!

Many Brooklyn parents find that once their kids start Martial Arts classes, they see a happier, more social child develop right before their eyes. You’ll be glad they started classes!

PLUS…. Most kids LOVE being a ninja!
