Posting a picture of where you are currently would greatly aid all of us guys, err, personal trainers, in assisting you to reach your laudable goals of rounder and firmer breasts. LOL
On a more serious note, my failry busty wife lost a lot of body fat (she wasn't even fat) and most of it came from her breasts. After doing as much chest work as possible we came to the same conclusion MANY
female bodybuilders come to- extremely lean means you will turn your fun bags in to ski slopes.
We are opting for a lift and enhancement to return her to her full glory.... 8 grand, 5 for the implants and 3 for the lift.
Best of luck!
