I know what u mean about breasts.I have always had big breasts.A lot of women think its a good thing but it really sucked when I was only in the 4th grade, wearing a C cup.It really hurt my self esteem.But now that i'm 26, it's not so bad as long as I take care of them.The best thing I have ever found to work on keeping the chest area tight and lifted, when u have large breasts-- PUSH UPS.I swear by it.I do a lot of cardio and weights but the push ups make a huge difference.I do a a lot of push ups.When ever I stop doing push ups for over a week, I feel my upper half falling a little south, even with still doing weights.Push ups.I swear.
