Is it possible to resume heavy weight training after breasts have healed from breast implant surgery?

Waiting
6 weeks after breast augmentation is the general rule before vigorous exercise.
Discuss with your surgeon the wisdom of potentially going over the muscle
rather than under the muscle with the implants. I operate on a number of
bodybuilders and often times they will prefer this look so that the breast does
not twitch and raised with flexion of the pectoralis muscle.

Once everything has healed and the pocket around the implant is formed you can return to all a activities. I would usually suggest not to do pec training for 6-8 weeks to minimize the chance of implant malposition. 

Thank you for the question. I advise my patients to resume weight lifting after 6 weeks and to start gradually to build up the weight. Best of luck with your surgery. Dr. Khuth
