Obviously I’m going to disagree that Krav maga is ball shots and hair pulling.
But think of it this way - you’re defending yourself - at some random bar, someone puts you in a headlock, guess what - I don’t care who the hell you are I’m going to beat your ass anyway I can. i punch you in the balls which shocks you and then elbow you and knee you till your face is red with blood, I saved myself a broken neck.
How long have you studied it? If you haven’t - don’t talk shit about it…
If you want to look at shit like that, xambo is nothing more than 2 guys figuring out how to huge each other differently.
