Some believed it was:
A neck massager
A stretching device
An exercise machine
A beauty accessory
A luggage holder
A shoulder trainer
A piece of ergonomic office equipment
A physical therapy device
A futuristic clothes hanger
Others weren’t quite as serious.
Some joked that it looked like an alien invention.
Others compared it to props from science-fiction movies.
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.
How Does It Work?
The device is surprisingly simple.
The curved padded section is positioned comfortably between the legs while the user applies pressure by squeezing inward with their thighs.
The side handles provide resistance and stability during the exercise.
Depending on the specific model, some versions include springs or resistance bands that increase the amount of force required to complete each repetition.
The movement targets muscles that are often neglected during everyday activities.
Many people use it while:
Watching television
