Unrealistic body standards are a known issue. Yes, fit women exist, but I'm betting there aren't plus-sized mannequins in yoga pants next to this one. But there absolutely should because, hey, exercise is good for everyone.
The "west has fallen" angle cracks me up. It's so full of dissonance, I can't even.
Edit: the weird lighting had me thinking that was a plastic mannequin and not a real person. That's just incredible.
Unrealistic expectations are absolutely a thing and we should promote normal physiques.
Also, being fat is absolutely a thing and we should promote not being fat.
Caveat: some people say "plus size" to mean healthy weight. Some people say "plus size" to mean fat/overweight. Being overweight is a significant health risk, and I say this as someone who is overweight and trying to fix it.
