The year is 2014, and thanks to technology’s relentless progress—which has lately brought into being, among other things, an app that tells you what song is playing, refrigerators with Wi-Fi, and make-believe currency—the world is truly becoming a more advanced place, and one full of possibilities beyond the wildest imaginings of our forebears.

Just ask Jen Selter, who launched to Instagram fame (where cats with strong personalities, toddlers with off-the-runway style, and midwestern cheerleaders have also found their place in the cultural conversation of the Internet) for her #belfies—er, that is, her butt selfies. Selter’s derrière extraordinaire has made her a member of a rapidly rising subset of Instagram stars: young women unafraid to share their deeply bronzed, sculpted figures in neon spandex, who want to share their #fitsperation thanks to #cleaneating, #determination, #cardio, and so much more #hardwork.

That’s right. Selter is here to inspire. When fans recognize her #seltering—posing for her iPhone with a leg raised and buttocks in full focus—on park benches and subway stairways, they tell her she’s inspired them to go to the gym that day. And for that, it’s all worth it. Along with the knowledge that she has sent one more young woman to the treadmill, she’s also raking in sponsorships, free gear, and, most importantly, followers by the thousands. The catcallers, the X-rated commenters, the feminist critics, though? File them under #haters.
