In the post, Rymill describes her first session with a personal trainer and being told, "Obviously, you want to get back to your pre-baby weight."
"It wasn't a question, it was a statement," she wrote. "And it pissed. Me. Off."
So, Rymill corrected her by saying she was less interested in losing weight than regaining her core strength and endurance. But the comment really made her think about the societal pressures put on women to get their pre-baby (or, as Kerry Washington so aptly calls it, "pre-miracle") bodies back.
But it's not just mothers who feel this type of pressure, she wrote. "Skinny people are envied for their lack of fat or shamed for apparently starving themselves. Voluptuous women are either labelled fat and shamed or they're labelled brave for being comfortable in their own skin."
Describing the photo she posted, she said, "My hair is greasy, I have no makeup on, my body is squishy and plentiful, I'm not even sure I'm totally OK. But I am strong. My body is healthy. Hell, I am badass as fuck!"
Rymill concluded her post with a call to action — "Join me if you will #badassundies" — which inspired many other moms to share their own underwear selfies using the hashtag.
This is a movement we can get behind, and clearly other people agree: her post now has upwards of 6,600 shares.
