Doing the splits. Rock-hard abs. Hotter than hell. Oh, and as the best ever in her game, about to compete for a Grand Slam.
We are not worthy.

Not my type but certainly a type worthy of note.
Yes, she’s awesome.
Even the dog thinks so - just look at the expression on his face!
She’s a great tennis player and a great athlete but I don’t find her attractive.
I don’t find her attractive at all. I never did like masculine/muscular women.
I know there are guys who dig muscles on women. Not my cup of tea.
All muscular women? They aren’t allowed to have them? Or is there a particular type of muscle that is allowed?
Muscular women just aren’t appealing to me. abs, biceps whatever.
A woman can be fit without bulging muscles. But that’s just my imho. YMMV I grew up in the seventies and my sex symbols were Cheryl Tiegs, and Christie Brinkley. Totally different body types from today’s women.
I understand Serena is a champion athlete and needs those muscles. I like watching her play tennis. But she does nothing for me otherwise.
I don’t like bodybuilders of either gender. But her body is purpose built and her achievements amazing. Gotta respect that and her hotness is driven by it.
Mark me down as another person that doesn’t find her attractive at all. Not the muscles either; I can find a muscular woman to be very attractive. I don’t think she’s pretty.
“So… do you work out?”
Just…no.
I was always slightly more fond of Venus than of Serena.
But… Yeah! “Musclegirls.” Yum! I’d love to have a sweetums who could knock me out with one punch…because I’d always know she wouldn’t!
Can women look good with six-pack abs?
Oooooh, yes…
I appreciate the beauty of her body and the work she’s done to get it in that magnificent shape. Her body is truly a sight to behold. For me it’s the same feeling I get when I look at, say, Brad Pitt’s shirtless body in Fight Club. Does nothing for me sexually, but holy crap that’s an amazing specimen of human.
ETA: Although, if I were single I definitely wouldn’t push her out of bed. Brad I would. So there is a difference, I suppose.

Now, Gina Carano… I would love to have her rough me up a little. 
Like Shannon Doherty or Mariah Carey her craziness is offputting.
That’s your threshold for “craziness”? An athlete frustrated during competition expressed that by verbalizing a violent fantasy and using the word “motherfucking” twice? Man, you don’t wanna meet any of the women in my life. That doesn’t even rise to the level of annoyance at the alarm clock in the morning, let alone to the level of annoyance when she figures out she’s outta coffee.
She looks like she could crack open coconuts with her thighs. That’s scary. She is an incredible athlete, but despite the makeup and curves, I find her very masculine.
“Crazy” or not, it’s off-putting as hell. Even John McEnroe was impressed by that one. And she justifies it by implying that we’re singling her out for criticism.
She’s rather charming when she’s winning, though.
