Can I exercise my chest muscles with weights after explantation?

After breast explantation surgery, it's important to approach exercise with caution. Generally, you should wait until your plastic surgeon clears you for physical activity, as the timeline can vary depending on your individual healing process.
Typically, plastic surgeons recommend waiting at least 6-8 weeks before resuming more intense activities, including chest exercises with weights. When you do start exercising, begin with lighter weights and focus on proper form to avoid straining the chest area. Always follow your plastic surgeon's advice recommendations and listen to your body to prevent any complications.

What you are describing is known as animation deformity and results from the pectoralis muscle pulling on the capsule where your breast implant previously resided. In my opinion, exercise should not cause any problems at 8 months post-op and should not worsen any deformity (except while you are exercising of course). It may be possible to perform a revision surgery to decrease the degree of animation deformity. However, I would seek several opinions from qualified plastic surgeons before embarking on additional surgery.
