Some say thigh gaps are hot, others don't even know what they are. I wanna know if they're healthy.
That's really weird. I've got a thigh gap lol and I think I'm pretty healthy
They aren't necessarily healthy or unhealthy, they are a physical trait that some people have & others don't.
That being said, I believe most mainstream standards of beauty cultivate unhealthy attitudes.
As a fitness goal, they're silly at best, and yeah unhealthy at worst.
They're linked to body type & bone structure. For some people they're just impossible, or only possible after literally starving, so yeah, for those people it would be unhealthy to fixate on that as a goal.
Beauty, and more importantly health, comes in all shapes & sizes.
