I have quite big rib cages, will have big rib cages make it impossible for me to have a slimmer body, or waist? i'm 5'2 and weigh 120 pounds

Where: If you have a big rib cage, your chest will always be larger than average. On the other hand, a slim figure is usually better defined by the waistline which is not necessarily correlated to your chest size. The size of buttock is harder to control but is still affected by how much you weigh.

Not really.: Do you have a large rib cage because that runs in your family, or because it developed from your athletic or sports training? Your body mass index (BMI) is 23.9 which is in the ideal range, so you are already at a good weight. Being, looking, and feeling fit go a long way toward looking attractive. Then find the fashions that most flatter your body type. You go girl!

Rib Size: The size of your ribs, which are bones, will not change if you exercise or lose weight. The size of your waist can change however, as this is also affected by body fat and muscle tone.
