Can I do chest exercises (weights) after a fat transfer to the breast?

Thank you for your question.  Once the fat becomes engrafted (new blood supply to it), it simply behaves as normal fat.  Once the swelling has gone down, you are okay to resume normal activities.  This typically takes 4-6 weeks.  Definitely follow the advice of your surgeon.

I let my patients exercise as soon as they feel like it, which is usually 3-4 weeks after the procedure, but I recommend they start light exercise first and work their way back up slowly.

Hello,exercise will not make your grafts disappear any more than fat anywhere else on your body. As I said in your other post about bras, what's alive will remain alive, and what isn't will slowly dissipate with time. You can exercise as lib.Best of luck!
