KRL...
Krav Maga is taught in a co operative enviroment.
That means, no one is punching or fighting back.
I went to a KM/Combatives school where I lived in Canada for an intro class. When free sparring took place, I owned everyone. All their skill went out the window when a larger person got inside, took them to the ground and submitted them.
If KM was so good, why isn't it being used in the ring or cage for MMA?
The standard answer is, we don't do sportfighting, and it's too deadly for the cage.
BS, imho.
