I have an account on every social media network. It's kind of ridiculous. Specifically, things like Pinterest and Tumblr are mega time wasters, but I enjoy them, and find some good stuff from time to time. However, on these two particular social networks, the tag "Fitspo" comes up often, and I've had enough.
Being "Fitspo" is still thinking something is wrong with your body, thus, I'm not sure how it's "encouraging" or "motivating." By posting images under this tag that you think are "Perfection"--and perfection is unattainable--then you're setting yourself up for feelings of worthlessness. I know it's hard to love the body you're in--I struggle with it from time to time--but I would rather struggle then feel shitty about not being able to attain some fucked up standard of beauty/fitness.
Take a look at both images on the left. What is the difference? Both images show white women on the beach who are thin. The only difference is the tag they are placed under, "Fitspo" for the top one, and "Thinspo" for the woman on the bottom. Do the women in the photos know what their photos are being used for? Would they be happy about it? I would hope not.
"Fitspo" is still catering to the mainstream. It's still perpetuating beauty myths that women don't need! I know it's difficult to stand up to a society that tells us we're not good enough, but we simply must. It's too dangerous for us to feed into the mainstream's ideal. Join the Body Positive Movement--stop hating your body. Stop looking externally for motivation or encouragement. You have one body--take care of it, love it, honor it, accept it.
By being you, in your unique body, you are resisting cultural norms. You are powerful.
