Answers I typically hear are "I would kick him in the *****" or "I would punch him in the face" unfortunately, if an attacker sneaks up and grabs you from behind (which is most likely) those defenses are not an option!
One of the greatest things about Jiu Jitsu is the fact that it can help a smaller, weaker person defend against a larger stronger attacker, on or off the mats!
I am a 5'2", 115lb woman, could I escape if a 180lb man grabbed me? I feel pretty confident that I could and if not...I certainly would be able to make enough of an effort that I could most likely attract attention for help or scare my attacker off.
Brazilian Jiu Jitsu helps women avoid dangerous situations and empowers them with simple escape techniques. It is designed to help a woman save herself from her attacker, whether she is on her feet or on the ground.
Brazilian Jiu Jitsu involves submission and ground fighting techniques. It focuses on gaining a dominant position over your opponent with the help of techniques such as chokeholds, joint-locks, compression lock, etc. Most martial arts need the practitioners to be physically strong to face a heavy-weight opponent. Brazilian Jiu-Jitsu needs more of body mechanisms rather than strength, speed and weight of the person practicing it. They can therefore be used effectively by anyone of any age, size, strength or level of physical fitness.
A common way for men to win a fight over women is to knock her down to the ground and control the whole situation. The ground fighting techniques of the Brazilian Jiu-Jitsu focuses on acting against your opponent with your back on ground plus taking the advantage of the right situations and poses of the opponent.
It's also great for losing weight, getting in shape and feeling confident and empowered!
