What training techniques does Barcelona use to increase stamina?

Techniques a short girl can use to defend herself in a fight?

• So, school is about to end and im heading back to my home city. Unfortunately, there are many troublemakers there who like to start fights and pick on small people. You understand, low income neighborhoods with reckless kids. Of course, I don't want to fight but im starting to realize that while I live near these places its unavoidable. The point of this story is, im 5'3 and as tough as a marshmallow (im thin and just plain fat ). Ive gotten into plenty of physical fights but I dislike getting into them since I get beat up badly. These people I fight are usually taller, experienced, more body mass and thus strength. Im not asking for methods to win but at least ways to lessen the damage. What are some effective methods that a short girl like me can use in a fight, at least to reduce their stamina or power? I have no experience with combat training and the fights are just street fights. Im not proud of this question but feeling vulnerable can take a toll on ones self esteem. I dislike feeling scared when im threatened with a fight. Afterwards, i feel like wuss although I know I shouldn't feel this way. Thank you for reading post and your answer.

• Answer:

  First things first you probably should not go to the places you are going or hang around the crowd you are hanging with if you have to worry about fighting, but if you don't want to change your friends or places you hang out, take some boxing, self defense or martial arts lessons, in most low income areas you can get them cheap if not for free, this will increase your confidence and also get you in great shape, now if your lazy this is not gonna work, but if not lazy it will change your life.
