"The market" seems to demand women have asses like prepubescent boys

[mythology]

107. I know multiple adult women who are athletes who have what can be called small asses

One of them even didn't realize she had her pants on backwards because she really doesn't have a protruding ass. She's also an amazing athlete who made it to the Las Vegas taping of American Ninja Warrior. I've watched multiple women with the same body type do rope climbs with just their arms (which I as a guy can't even begin to do).

I know another woman who grew up playing soccer, turned to gymnastics in her 20s and while she looks like a stiff wind would knock her over is working on the upper body strength to do a manna.

For reference a manna is: A strength move pressing with the hands where the legs and hips are raised until the hips are above the shoulders and the legs are parallel to the floor.

Not all skinny women are anorexic nor are skinny women not athletic.

I haven't seen the SI cover, mostly because I don't care to. But to say that women who are naturally very skinny are inherently unattractive, or look like prepubescent boys is just as biased as saying that women who have more curves or have the proverbial Jennifer Lopez backside are fat or inherently unhealthy. Different people have different body types. And most of them can be attractive and healthy.

For example all of the women in the photo on this site are all Olympians and yet they have a wide variety of heights and weights.
