I will mention a few things that will be positive news for you folks, and other things which will naturally be bad news, but I'll start with the positive.
Thanks to characters like She-Hulk, Powergirl, Wonder woman, and anyone you can think of that may sometimes be depicted with muscles. Comic book readers are much more accepting of female muscle and FMG than the mainstream media. After all how many times have they seen She-Hulk transform from Jen Walters into Shulkie? Most comic book fans are much more accepting of it, and where there are comic book fans there is sometimes mainstream.
At the same time, the advent of youtube has brought a huge collection of FBB's for the mainstream to enjoy. Though most of the times even the most feminine body builders will get comments like "Whoa she's a man." Or the most popular "She'll crush my penis." There have also been some converts who have said, "I normally don't like muscles on a woman, but I'll make an exception to her."
This suggests that over time female muscle is becoming more and more accepted even by mainstream standards.
HOWEVER!
Even though a lot of things are pointing towards a positive direction it is still taking an extraordinary amount of time to actually reach that point. People still will be grossed out by the concept of a muscular woman but at the same time the more they are exposed to it the easier it is to accept it.
This is after all how the media influences the world, the more exposure we can get for FBB's like super size she, youtube, She-Hulk, cameo appearances in TV shows, then the greater possibility for female body builders to be accepted by mainstream.
FMG however, whoo... now that is something I don't forsee being accepted for the next 50 years. A woman hulking out to the size of the incredible hulk is something that I don't think will ever be accepted in mainstream media.
Now however, if you have a woman FMG'ing into a perhaps "smaller" more realistic bodybuilder, like say Jodi Miller into Gina Davis. The transformation would have to be done in a more sensual, sexual, and arousing way; with less focus on violence and more focus on sex appeal.
So it would probably be close ups of the breasts growing, sleeves ripping at the shoulder, while having the actress panting almost as if she were in ecstacy. I bet a LOT more people would be accepting of FMG if it were done in that manner; even if they did see a bicep explode from the sleeve they would certainly want to watch it again.
However, even THAT would still turn off a huge amount of mainstream folks. Sure it would convert a couple but that's something that the mainstream media just isn't ready to accept. It's going to take a few years of bombardment from the media in order to get female muscle acceptable, once it reaches that stage then it would progress into FMG; but I highly doubt that will ever be acceptable in mainstream.
If you're wondering how I got my info, I've been doing research on this topic for several years. Using that data I've got I'm hoping to experiment with people's reaction if I created a character that was muscular, but you didn't notice until halfway into the movie. If people fall in love with personality, will they forget that the character has muscles?
I'll keep you updated on that experiment
