First, remember that prevention is the best self-defense. Attackers, whatever their objectives, are looking for unsuspecting, vulnerable targets. So be sure to follow general safety tips like being aware of your surroundings, only walking and parking in well-lit areas, keeping your keys in hand as you approach your door or car, varying your route and times of travel, and other personal security precautions. Apart from avoiding confrontation, if you can defuse a situation (talk someone down from physically assaulting you) or get away—by handing over your wallet/purse or whatever they want, do that. Hand over your money rather than fight. Nothing you own is worth more than your life or health. If violence is unavoidable, however, to really defend yourself, you'll want to know ahead of time how to fight back effectively—it's possible even against someone bigger or stronger than you. Here are some basic self-defense techniques that can keep you safe: Get Loud and Push Back
As soon as the attacker touches you or it's clear that escape isn't possible, shout loudly ("BACK OFF!") and push back at him or her (for simplicity's sake we're going to use "him" for the rest of the article, although your opponent could be female). This does two things: it signals for help and it lets the attacker know you're not an easy targetIt may not dissuade all attackers, but getting loud will warn off those that were looking for easy prey.
