Might be worth making a list of inactive and semi-active ones.  Unless you just want to join for past content, which I guess some people will.

Lexa Stahl has 1 post this year, Jessica Williams only 8, just for example.

Is Ripped Reilly no longer a member? Her link goes to nowhere.

Lovendahouse aka Lena Love aka Miss Daniels, physique competitor, performance artist, and sessionette. I've met her, and found her stunningly beautiful in person. She's never done much traditional muscle media, so she's not overexposed. If you like her look, her new OF is the best place to see her. About half of her media is nude or topless. Well worth the current price of $5.99.

Annie Doll (FBB Anne S.), that's a tough one. A few topless clips, but filmed so you can't see anything. The rest is bikini/tank top posing and workout. For ten bucks, I'd certainly recommend anyone who's a fan to sign up for a month just to support her, and have a voice in what you'd like to see.

Decent content on this one, UK girl -

Forgive me if this was already posted here, but the gorgeous physique pro Emily Schubert started a page in February. Not much content for the $15 per month yet, but she told me she plans to start posting a lot more and wants to show her prep progress and use this to interact with fans. Emily looks amazing in contest shape, but I really like her offseason shape too. Great lats and quads, and abs! Check it out here:

Decided to check her page out.  She's got a decent amount of content so that is worth the $15 sign up fee.  The problem is her page is full of little snippet clips of longer versions for an additional fee.  Many of the clips are less than 30 seconds. 

I was gonna buy a longer version from her but her asking price shut that down real quick.  She wanted £120, which comes to $150 for a 5 minute clip!  That's just ridiculous.  Who is crazy enough to pay that for a 5 minute camera phone clip.  Ain't no FFB in history worth that kind of money.

What happened to the good ol' days of buying 2hr WPW videos for $60?

This one was very speculative for me. At twenty bucks a month, it's not that cheap, but she's from my home state which is getting hit hard, so I decided to support her. By the numbers, she's got decent amount of content, but it's worthless. It's the most skin you'll ever see without seeing anything at all. But if watching a woman using all of her ingenuity to ensure you'll never get an unobstructed view of her nipples is your thing, she's your gal. Not that I need nudity to appreciate a muscular woman, but she's a fail there as well. She's got a couple of pictures showing her physique, but no videos. As far as I can tell, there's not a single biceps flex in over two hundred posts.

She's scared of losing her vanilla T&A fans who somehow don't realize she's muscular. If you ask her in pm for muscle pics or vids she'll deliver, of course it will be for additional $$. Why people like her who work out for hours every single day don't embrace the fact that they're muscular is beyond me. I guess the money for pics of tits is more than what she can get from muscle fans. She has a lot of followers, she'll be fine whether you support her or not. Very reasonable not to want to spend money on subscriptions and muscle posts in DM.

IMHO
I am some what different. I don't like when women with muscle have a site like this and all they show is nudity. I like nudity and XXX as much as anyone but if I joined her onlyfans page and all (or most) she has are videos of her and her boyfriend having sex or her with a toy, I feel ripped off. I was a member of queenkarma18 site for a month but almost all of her stuff is her with a toy or something like that. I had asked her to do more muscle but she said she can only do so much because guys don't want to see it. (And she has some *really* nice biceps BTW) I have never been able to figure that out. Guys go into a chat room or sign up for a web page of a women with muscle but they don't want to see her muscles. They just want her with her legs open. Or even worse, and this is something 99% of female muscle sites are guilty of, they have her "posing." But it is not flex posing, its sticking her butt out and trying to look sensual (or something) posing. And make no mistake, I LIKE THAT STUFF TOO. But it should be part of it, not the whole of it. If that is what you want, there are many places to see that. (I may be there myself) But to join a onlyfans page with a fit or muscle woman's picture in the profile, then join the site (i.e. pay money) then say you don't want her to show her muscles.......

It also adds insult to injury when the lady "markets" herself as a muscle woman but the guys who join her site don't want to see her muscles. One of the few times in history the women listen to what the fans want, and the fans she listens to don't want muscle

I feel (and I'm sure I'm not alone) as though I've had to weed through websites like streammate or some other adult site trying to find fit and muscle women. But with the way things seem to be going, I now have to weed through the sites of the fit and muscle women trying to find a woman who is showing muscle
