I need your help...I am 20 years old,5'9" and 127lbs.I know I am very skinny and I am sick of that and want to change it.I am pear shaped and my lower body is heavier and larger than the upper .My arms and shoulders are skinny,my breasts are flat...I hate the bones on my chest that are visible.I feel very depressed because I would love to change my "model"(as people tell me) body with a more curvaceous and feminine one but unfortunately I know I can't...Now I would describe my lifestyle as healthy;Clean eating and exercise(I eat many cals but only clean foods and that's why I have a low body fat and thin body).The last months I go to the gym and lift heavy for the upper body.I also take protein supplement after gym in an effort to make my muscles give the illusion of a more full upper body...Although I can see some definition on my arms and shoulders ,unfortunately I am still very skinny.I want to gain some weight but I am afraid because I know that it will all go to my butt and thighs and will create saddlebags and cellulite while the upper body is still going to be skinny(unless I gain more than 20lbs).So is there anything you can suggest to improve my physique?Can I possibly grow bigger but still maintaining a nice body shape?I know DNA is not on my side,but I would like to do sth.Please help me...Eveyone blames models for being sickly thin ,I am like that but it is not my choise,it is genetics and I want to change it but I can't...Any recommendations are welcome
