I have had two sets of implants. The first set was back in 1993 and they were saline placed beneath the chest muscle wall. I was lifting back then, as well. BUT, they were sooooo uncomfortable all of the time, even while showering with no signs of capsulation. I had them replaced 1 1/2 yrs ago with silicone. I know, I know......everyone has their opinion of them. However, I love them. I feel as if I don't even have implants! There is one problem though. When I do any upper body posing, they lift up and out, good God, that bothers the hell out of me. My doc told me that they probably shouldn't have been placed beneath the muscle because of my bodybuilding. They told me that tends to happen to "us" but they were more concerned over me having clear mammograms. So, I guess I shouldn't complain. You may want to check with your doc because my saline implants had rippled and were rubbing??? Anyway, hope this helps you a bit. Good luck!
