What is unnecessary?I think Krav Maga is highly effective self-defense ( self-defense) with direct attack techniques without frills or nonsense ( unnecessary ) techniques. Also the generic term of combat systems of the Israeli armed forces, and various civilian self-defense systems.To be able to use in official and civilian field techniques have been modified and adapted to teach police and civilians ( self-defense , etc. )
Also offers the Krav Maga by a good workout the opportunity to increase his physical and mental fitness.
