Question: how long does it take to earn a black belt in krav maga?
Answer: I think that you might need between 3 to 6 years of continuously training to deserve a black belt in the original Krav-Maga system (the one that was developed by Imi Lichtenfeld and practiced in kimono). It took Imi 3 years to train his first and only one group of 10 Krav-Maga instructors.
