    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 4

    Focus

    Drills get longer. Attention gets stronger. Parents start hearing it from teachers before they hear it from us.

    Chapter 2 of 4

    Respect

    Bowing in, helping a smaller partner, holding the door. Discipline stops being a rule and starts being a habit.

    Chapter 3 of 4

    Self-defense

    Real skills, taught safely. Your child knows how to stand, how to move, and how to walk away, and they know they can.

    Questions parents ask

    Your first visit is a private Parent/Child Orientation Lesson, 30 to 40 minutes, with just your family and a K3 instructor. Afterwards we talk about goals and the right program. There is no obligation to join. Signing up yourself for Teen & Adult Krav Maga? Your first visit is the same private 30 to 40 minute lesson, one on one with a K3 instructor.

    Comfortable clothes you can move in and bare feet. We train on mats, so no shoes are needed. Bring a water bottle.

    Most first-timers are nervous. That is why the first visit is private: no crowd, simple drills, and an instructor who lets them build at their own pace. Shy kids often surprise their parents.

    Yes. Our Teen and Adult Krav Maga program is built for ages 13 and up, at every fitness level. It is practical self-defense with honest conditioning.

    Krav Maga, Karate, MMA, and Kickboxing. Programs blend them by age and goal, so kids learn control and coordination while adults focus on self-defense and fitness.
