I'm glad Samantha still is showing off her physique. It seems that many fitness/muscle models get larger implants and then abandon it to do glamour or porn (Krisztina Sereny comes to mind of recent).
Or conversely, someone with implants takes up fitness and gets in fantastic shape, then tones down the glamour. (This could be for practical reasons, because a common fitness job is a trainer, and if you're an adult film veteran, you might not get hired by a local gym?)
I figure if you have the physique and the implants, flaunt both, and Samantha does
Anyhoo, just a thought.
