🥋 STRIKEBACK BRING A BUDDY DAY! 🥋

📣 Hey, Strikeback students! Who’s ready to bring a friend to class?

Karate is even more fun when you share it with a buddy! 👊 Bring a friend, a classmate, or someone you think would love to try something new, and let them experience what makes Strikeback so special!

💥 Beginners: 10/21
💥 Advanced Class: 10/22

Your buddy will have the chance to learn new skills, build confidence, practice discipline, and have fun alongside you!

Remember, being a great martial artist isn’t just about how hard you can kick or how fast you can punch. It’s about being a leader, showing respect, encouraging others, and helping those around you succeed. This is your chance to be a leader and introduce a friend to something awesome! ⭐

Martial arts is about so much more than learning how to defend yourself.

It teaches you to set higher expectations for yourself and understand that anything worth having takes hard work, perseverance, and commitment.

Every new rank is earned through consistent effort. You learn to push through challenges, stay focused, and keep working toward your goals—even when things get difficult.

Those lessons carry far beyond the dojo. The discipline, confidence, focus, and perseverance developed through martial arts can help you excel in school, your career, and other sports, while building the life skills needed for everyday challenges.

We’re not just teaching martial arts. We’re building empowered individuals.

Stop in, Strikeback Karate, shoot us an email @ [email protected] or give us a call @ (603)262-9299 to set up your introductory lesson!
