One commenter even suggested it resembled “something astronauts use to exercise in space.”
The creativity of the internet was on full display.
Despite hundreds of different theories, very few people correctly identified the device.
So What Is It?
The mysterious object is actually a thigh exerciser, sometimes called a pelvic floor trainer or inner thigh fitness trainer.
It’s designed to help strengthen several muscle groups, including:
Inner thighs
Hip muscles
Pelvic floor muscles
Core muscles
Glutes
Although it’s commonly marketed toward women—especially for postpartum recovery and lower-body workouts—many versions can be used by anyone looking to improve lower-body strength and muscle endurance.
Its unusual shape suddenly makes much more sense once you understand how it’s used.
