The first 90 days
What actually changes
Confidence
Your child stands taller before they can throw a proper punch. We start with eye contact, a loud voice, and a coach who calls them by name.
Chapter 1 of 4Focus
Drills get longer. Attention gets stronger. Parents start hearing it from teachers before they hear it from us.
Chapter 2 of 4Respect
Bowing in, helping a smaller partner, holding the door. Discipline stops being a rule and starts being a habit.
Chapter 3 of 4Self-defense
Real skills, taught safely. Your child knows how to stand, how to move, and how to walk away, and they know they can.
Chapter 4 of 4



Ages 13+
