I have studied a ton self defense and the best thing you can do in this position is to find ab escape route asap
The first second they approach you analayze and decide you are screwed real quick and dont let them surround you and look for the escape route as soon as you find the escape route opening....strike the closest guy in the throat but if u dont have a clear shot then do and open palm strike right to the nose and run. This is harder said then done but you have to do all this before they get confident and comfy. You have to access analyze and do the first strike as quick as you can.
The key is you really have to learn how to strike. If you know that you can really do damage with a single strike and buy yourslef a few seconds to run and scream and cry for help. Its sounds girly but you cant mess around with 7-1
If anyone wants to learn and practice proper striking let me know. I used to teach people for free on kijiji. I am happy to practice with anyone. Everyone should know how to defend themselves and striking is like anything else the more you do it the better you are.
True, never have opponents behind you. Plus if you can find a narrow corridor, that should bottle-neck them.
I have a Black belt from Mortal Kombat and Streetfighter. Can I come practice those moves?
