Yes, a submuscular implant will move and look more defined when you flex. If you work out a lot you should discuss the possibility of a subglandular placement (above the muscle) with your surgeon.

Movement of the implants can happen with subfascial placement. There is really very little support when implants are placed this way. Unfortunately, other than have a secondary surgery to have the implants placed differently, there is no way to get rid of the issues you've mentioned. The only suggestion I can offer, which you may have already tried, is wearing a sports bra with a lot of support.

They can sometimes feel more natural than under the muscle. When you flex, the muscle flattens out and pulls the implant laterally. That is normal. No movement means you have a capsular contracture.

Thank you for your question. The implants should not move if they are placed in a subfascial placement properly. You should consult with your surgeon. Good luck!

When a breast implant is placed under the muscle, every time you contract your muscles, like curling weights, it will cause distortion of your breasts. It does not cause a problem, just looks unnatural!

Thank you for your question. This "flexion deformity" can happen with breast augmentation surgery. I suggest that you visit with your surgeon and discuss your concerns and see how he/she can help you improve things. Best wishes.

Movement of the implants and your breasts with strong pectoralis constraction is normal after partial sub-pectoral implant placement. The amount of movement varies depending on your anatomy, how you healed, and the degree of muscle release from your rib cage. Under-the-muscle implant placement is typicaly performed by releasing the lower end of the pectoralis from the rib cage. It is not sewn back to the ribs. It still functions but now when it contracts, the free lower end will move upward and outward, which is what you are seeing. As I said, it differs in the degree to which it happens in patients and 1-2 cm is not a lot. In severe cases, the implant can be changed to an over-the-muscle position to correct the problem or there are a variety of implantable materials ( Alloderm is one ) that are used to stabilize the end of the muscle to the rib cage so that it will not move as much.

That seems to be typical when the placement is under the muscle. See your doctor for follow up. All the best.

Since you weight train, subfascial breast augmentation was a good choice for you. There should be minimal movement with flexion of the pectoralis. However, if you are very lean, there is a chance that your surgeon chose to lift some muscle fibers up with the breast flap both medially and on top to cover the edges of the implant as best as possible. This can lead to some movement, but it is likely far less than what you would have experienced with a submuscular implant.
