You know... most people interested in her aren't into her body or her muscles. They're there for the music. They like Nightwish and banging their heads to the guitars.
Furthermore, if you actually follow these bands, it's pretty rare for any metal star to post about their workouts. There was one band that posted a picture or short video of them working out in a parking lot or something while on tour.
Anyway, she's really not that muscular. Certainly not by the standards of these forums. Sooner or later she'll get kicked out of Nightwish, and many people will forget about her.
