FAQ
Frequently asked questions.
Do I need any experience to start jiu jitsu?
No. We train adults and kids from beginners to competitors, and every new student starts with a free private intro session with one of our coaches, where we answer any questions you have about jiu jitsu.
How old does my child need to be?
Our youth program covers ages 2–16: Parents & Kids (ages 2–5) on Saturdays, Mini (ages 3–6), Kids (ages 5–14), and Youth Competition practice for kids who want serious mat time. It blends jiu jitsu, wrestling and judo.
Do I have to compete?
No. Even if competing isn't your goal, we offer more competitive-style training for anyone interested. Our comp classes are open to everyone.
Is there a women's-only jiu jitsu class in Manassas?
Yes. Every Friday at 7 PM we pack the mats with women only — a welcoming space for women starting their jiu jitsu journey and a serious training room for competitive women. It is led by our Women's Head Coach, Caitlin Ghalayini.
What is the difference between Gi and No-Gi classes?
No-Gi is a one-hour class mixing warm-up, curriculum work, and both positional and open sparring, with no gi required. Gi classes follow the same format wearing the traditional gi (kimono).
