Breast Distance Exercises. Is there anything I can do to reduce the gap?

I am 1 month post-op from 34A to 34D with silicone 385cc. My implants have settled really nice thanks to a talented surgeon. My only question is that the implants do have that gap between. I understand that there will be gap. Is there any exercises or techniques that you tell your patients in order to train or minimize the gap? My doctor told me to hug myself but maybe there is a more aggressive way? Thanks in advance!
