Hi and welcome
Cool, I have wanted to help out someone put on some size instead of lose fat.
Would it be possible to get a bit more info, like your training split, what exercises you are doing for your legs and each body part?
Do you put on fat easily or are you one of those type of women that can eat a lot and not have to worry too much?
You may have to put on a wee bit of fat to put on some muscle, but not much. You are at a perfect bodyfat right not for mass building BTW.
