Building Pectoral Muscles Before Breast Augmentation?

We generally advise patients to cease from pectoralis strengthening for 2-4 weeks prior to surgery to decrrease bleeding and swelling of the engorged muscle.

This really isn't going to make a difference as the amount of muscle that you may add won't significantly affect the overall size. Also, if you're getting the implants placed under the muscle you may want to avoid any heavy chest building exercises so that your recovery is easier. Getting the implants over the muscle will give you an easier recovery, but you may see the outline of the implants more. Good luck!

It will not make a difference in recovery. So you can go ahead and do your weight lifting and be rest assured that it will not make your recovery and more or less painful. What works well during the recovery phase is muscle relaxants and make sure your surgeon provides a prescription for some in addition to the pain medication that you are prescribed.
Good luck.

Most breast augmentations are done by placing the implants under the pec muscles for a variety of reasons, but whether they are bulked up or not should make litle difference in the early recovery. However, if you are a body builder or athletic, there are issues that are more important long-term with implants under the muscle. One common example is what are called "animation deformities" in which the breast is distorted every time the muscle is flexed. A variation of the subfascial technique can help minimize this.

If you are having breast implants placed over the muscle, then it truly makes no difference. If you are having the implants placed below the pec muscles (which I do for almost 99% of my cosmetic breast augmentations), then it still does not make much of a difference! If will not make your surgery go better or worse and should not ultimately change your result very much or alter your recovery. In theory, your plastic surgeon may have to "fight harder" with your stronger muscle to get the implants under it, which may cause more stretching and ultimately more discomfort, but in reality it really doesn;t work this way.
I would work your pecs if you like to and not worry about them with regards to your impending breast implant surgery.
