How does Krav Maga compare to other martial arts?
Krav Maga is not a martial art - there are no rituals or forms, there are no uniforms or codes of conduct. Simply put, it is a street fighting system built on a simple concept:  Negate the immediate threat, quickly go on the offensive, and get away safely. You’ll learn the basics of fighting: stance and movement, punches, kicks, knees, elbows, defenses against common street attacks like chokes, punches, kicks, bear hugs, take downs, guns, sticks, knives, etc, and increase your awareness of potential threats and how to avoid them before they happen.

Is there a belt system and tournaments for Krav Maga?
Krav Maga has no competitions or tournaments because we train for the street situation, rather than trophies, recognition or the ring. Competitions have rules to ensure the participants’ safety (no kicks to the knees, no eye gouging, etc) - street fights have no rules.
Krav Maga recognizes experience level only for the purpose of ensuring that students have sufficient experience to handle advanced techniques and training. – we are all here to help each other to learn and become stronger and safer, not to compete against each other.

What does Krav Maga Mean?
Krav is Hebrew for close or contact, Maga means combat
Thus, Krav Maga = Close Combat or Contact Combat

I don’t have a martial arts or fighting background and this is my first Krav class - what can I expect?
Krav classes are intense, particularly at first. Our focus is to induce stress and fatigue so that when the time comes, you can still react under the worst circumstances. There some bumps and bruises associated with learning, but we’re all here to learn, not to beat each other up or compete against one another – so you’ll find that that classes are about camaraderie and respect, rather than competition.

What gear do I need for class?
Basic workout gear (Tennis shoes /sweats/ T-shirt) are all that you need for regular Krav classes.
Separate shoes for the mat, any kind of sport shoes as long as they are not used for the street.
Optional: Mouth guard, groin guard, shin guard, boxing gloves, wraps
Sparring classes require 14 oz. boxing gloves, a mouth guard, shin pads and groin protection.
