Will Weight Lifting Help Breast Shape?

Breasts are under the skin but above the muscle. Exercising will improve your muscle tone, but will not effect the shape of the breasts.  It is not possible to lift breasts just by weight lifting. 

Weight lifting is great to help build and define upper body tone. It will also aid you in losing total body fat, which may include reduction of fat within the breasts. However, weight lifting will not increase breast size, nor will it correct sagging breast skin.
