How to Keep Myself Fit?

[lilmzhln18]

Okay, I don't hate myself because of my weight/height, but I want to know what I can do to improve things.

 

First off, a list of the "essentials":

• I'm 14.
  
• I'm female.
  
• Height: 4'11"
  
• Weight: 105

So, I wanted to know what I can do to get myself "skinnier."

I'm not sure if I'm considered fat or not in our society, but I'm assuming I am.

 

In any case, does anyone who had had these problems know what I should do.

 

Advice on what to do?

Exercise techniques??

 

TIA
