Can bench pressing affect breast implants in any way?

Hello - your concern with how activity will affect breast implants is certainly one of the valid points discussed with your board-certified Plastic surgeon during a consultation. During any forceful chest or Pectoralis major muscle contraction, breast implants that have been placed under this muscle will be compressed and will appear to move.   Breast implants can also be placed above the chest muscle to reduce this appearance of animation.  However, this is only one of many factors that need to be evaluated during your pre-operative exam to make the best decision for you.   Breast implant augmentation for athletes can work well in this setting. I wish you all the best. 

I often perform breast augmentation on athletes. It is very important to follow the instructions of your plastic surgeon.  You may wish to find a plastic surgeon with expertise in working with bodybuilders and athletes. Most plastic surgeons with expertise in this area with have a specialized gallery and section on their website devoted to breast augmentation n in athletes.
