Hoyeon doing pilates is top-tier thinspo imo, so here is a little compilation (not chronologically organized). Her pilates instructor posts pictures and stories of her in action from time to time (@pilates.sun).
A blind item about Hoyeon supposedly refusing to eat at awards season events... Obviously not 100% sure if this is true, but it's past the end of awards season and it's clear that she's still alive and clearly doing well Not sure why the definition of health is eating at formal events where it's often a set menu that's (in my experience) usually not very good.
Featured on Variety's Actors on Actors (with Sandra Oh, but no comments on her )
Her legs... no words needed
Her waist looks so tiny here, even despite the oversized coat.
It's clear she takes her profession seriously and it shows with how she's been able to maintain. Really look forward to her future acting work. So lovely and talented
