The 5 Ways We Change Lives, For Both Kids & Adults

Our Arnold martial arts school might just seem like a place to get fit and learn self-defense...

Well, we do help people with that! But there are some more "subtle" things that happen when you train in our programs.

Here are a handful of those life-changing things people walk away with...

More Confidence

One of the first things both children AND adults notice when training with us is a big boost in confidence. And it makes sense when you think about it.

After all, martial arts is challenging. Yet when you persevere in the face of challenge, and come out on top, you realize you're stronger and more capable than you thought.

Realizing that makes you feel more confident. You feel more sure of your ability to handle whatever other challenges life throws your way.

This goes for kids, too. Their confidence boosts quickly as well.

Increased Focus & Mental Clarity

Since the techniques are new, they require your full attention. As you concentrate hard on listening to the instructor, following along with what they taught you, and then remembering what you learned when you get home...

...the intense concentration starts to naturally flow. It pours into all other areas of your life including work, school, and even other activities and sports you do for fun.

Adults are able to focus better at work, reaching goals easier while kids report doing better in school all around.

You’ll Get Fit

Each class is loaded with challenging, fun exercise. But because you're so focused on performing techniques, and having so much fun, you hardly notice it. Before you know it, the class is over, and you not only learned powerful martial arts...

... you got a great workout, too. Being physically fit boosts energy, mental clarity, and confidence as well.

Community Values

Oh boy, your family is about to grow... big time! We're a tight-knit group here and our students are all about support and friendship. As you struggle through tough training times, and laugh through wins and victories, you’ll have your martial arts family at your back.

Friendship, motivation, and high fives are a part of every class. As you train together, you and your classmates will form an amazing bond. It's truly great to experience.

You’ll Have FUN Again!

Reignite your passion for life in our awesome classes! No two workouts are ever the same and you’ll rock your body to the core with fun, functional movements.

Gain lean muscle, increase your flexibility, and learn dynamic movements which are super-secret to martial arts conditioning. You’ll never hear military style yelling and we don’t use body shaming, ever. Just fun, positive motivation so you can be at your best.

Our students work hard, but they play even harder! Laughing and smiles are part of every class.

You deserve a safe place, clean place to learn and achieve life goals! Whether your goals are to learn self-defense against bullies and bad situations or simply get fit. Hahn Center provides kids, teens, and adults plenty of fitness and martial arts classes with TONS of options all geared toward a common goal - building self esteem, confidence, and physical and mental strength.
