So I'm starting to loose a lot a weight and I know a lot of people are going to be rude and say "your complaining bc your skinny" but I'm coming to the point where I look sick like in the face . I did competitive cheer for about 6 years and I was 115 then a stopped  in may , so I loss a lot of muscle . I thought I would have gained more meat in my bones by now but I have just been loosing weight , I weight 100 pounds now I'm 20 years old idk if that normal I get iam really skinny and everything all the time and belive it or not it gets annoying . Does anyone know how to gain weight in the right places like my butt and boobs and legs I don't squats but they don't do much for me I want to gain fat not muscle bc I know what I look like with muscle and I don't like it , and please don't tell me to eat bc I eat a whole lot
