Your Questions,
Answered
New to martial arts? Here is everything you need to know about starting your journey with us.
General Questions
What age groups do you offer classes for?
We welcome students starting from age 3.5! Our Lion Cubs program is designed for ages 3.5–5, Lion Kings & Queens for ages 6–10, and Lion Teens & Adults for ages 11 and up. We also offer an elite Leadership Team program by invitation for advanced students.
Do I need any prior experience to join?
Not at all. Every martial artist starts as a beginner, and our instructors excel at meeting students exactly where they are. Whether your child has never taken a class or you're an adult starting for the first time, you will feel welcome and supported at Regulus Taekwondo.
What makes Regulus Taekwondo different from other schools?
Regulus Taekwondo is led by Kukkiwon-certified Masters who are former elite athletes with decades of world-class experience. Our philosophy goes beyond martial arts technique — we are dedicated to developing youth leaders who contribute to the Irvine community. Our Leadership Team program is one-of-a-kind, combining Taekwondo curriculum with real business and leadership training.
What should I bring to my first class?
Just bring comfortable athletic clothing and a great attitude. Once you decide to continue, we will guide you on getting the right uniform and equipment. Everything else we provide!
How often should we train to see results?
We recommend attending at least two classes per week for consistent progress. Many students find that martial arts quickly becomes the highlight of their week, and progress accelerates with regular attendance.
Do you offer a free trial?
Yes! We offer 2 Free Introductory Classes for new students. It's the best way to experience our community, our teaching style, and the Regulus difference — completely free, with no commitment required.
What is the Leadership Team program?
The Regulus Leadership Team is an elite, invitation-only program for students who show exceptional potential. Members not only advance their Taekwondo skills but receive training in real-world leadership, management, ethical decision-making, and emotional intelligence — preparing them to become the next generation of community leaders.
Our Leadership Program is especially beneficial for those high school students who are looking to add volunteer, team building and work experience to their future college application.
