Frequently Asked Questions

What age should my child start?

We offer structured programs beginning at age 4. Lil' Ninjas (4–7) builds foundational listening and self-control, while Youth Ninjas (8–12) introduces authentic Muay Thai alongside character development.

What should my child wear to the first class?

Comfortable athletic clothing — something easy to move in that handles sweat well. Bare feet on the mats. We will walk you through uniform and equipment once your child is enrolled.

Which class should I attend for my free preview class?

Whichever class matches your age group — we place you when you book. Your free preview class is a regular session on your program's schedule, so you train alongside current students from day one.

Is Muay Thai safe for children and beginners?

Yes. Our classes are structured by age and experience level, coached under a certified curriculum, and supervised closely. Contact is controlled and age-appropriate.

What is the class schedule?

We hold classes Monday through Thursday and on Saturday. We are closed Friday and Sunday. Specific program times are confirmed when you book.

I have never trained before. Will I be behind?

No. Most students start with zero experience. Our coaches build every class around fundamentals first, so beginners of any age can train alongside more experienced students.

Do you offer adult classes?

Yes. We offer Teen/Adult Muay Thai and Fitness Kickboxing for ages 13 and up, focused on authentic technique and structured conditioning.
