At Duncan MMA in Kingsport, TN, our Little Ninjas program was created to give young children the perfect introduction to martial arts in a fun, safe, and structured environment. Designed for ages 4 to 6, this class helps kids build the foundations of jiu-jitsu, kickboxing, and wrestling while also developing important life skills like listening, focus, and coordination.
Classes meet Tuesdays and Fridays from 4:30–5:00 PM, and students are welcome to attend as many classes per month as they’d like — all for just $50/month.
Our approach uses structured drills and playful martial arts-based games to build whole-body coordination, confidence, and discipline. Little Ninjas earn stripes on their belts throughout the year to recognize their progress and prepare them for future advancement into our full youth programs.
Whether your child is brand new to martial arts or just starting their journey, Little Ninjas is the perfect place to begin. Come see why kids love it — and why parents do too!
