As a kid Imi studied wrestling, boxing, and gymnastics. In 1928 Imi won the Slovakian Youth Wrestling Championship, and in 1929 the adult championship (in the light and middle weight divisions). That year he also won the national boxing championship and an international gymnastics championship. During the ensuing decade, Imi's athletic activities focused mainly on wrestling, both as a contestant and a trainer.   

 
1. SELF - DEFENCE 

Provides a complete range of techniques which provides the combatants with all the means possible in order to protect and defend themselves and overpower their attackers. It consists of defence against all types of aggression - be it punches, hits, kicks, strangulations, holds, armed attacks or threats (e.g. knives, guns, sticks, grenades, etc.). The student of Krav Maga also learns to apply different methods in varying situations, both familiar and unfamiliar, which may hamper the freedom of movement, such as attacks in the dark, in a seated or horizontal position etc... 
 
2. HAND TO HAND COMBAT 
 
Represents a more advanced stage of Krav Maga where one learns to neutralize one’s opponent rapidly and efficiently. This stage includes elements necessary for hand to hand combat situations, from combination of techniques used against assailants to tactics, from unexpected reactions to decoy attacks. It also includes the psychological dimension of combat. 
 
Krav Maga emerged in an environment where violence, mostly of a political nature, was rife. It has had ample opportunity to be tested and improved under real-life conditions, proving itself to be an ideal means of defending oneself in the face of extreme danger. This unique training method has received international recognition as an innovative and highly practical self-defence system, and more recently has been taught to U.S. federal, state, and local law enforcement agencies, as well as to different police units in South and Central America and in Europe. 
 
Krav Maga is a modern, practical and proven system of self-defence, carefully devised or the needs of our present day dangerous and unstable world. It is characterized by a clear and logical approach to self-defence and fighting confrontations, which enables one to achieve a relatively high proficiency within a short period of time.  
 
Krav Maga was thoroughly developed to be diversified, and thus is completely applicable to the military, law-enforcement agencies as well as civilian needs.
