Learn English: Hula Hooping Success: Body Shape Matters! (hard)

A new study reveals that an hourglass figure is ideal for effortlessly keeping a hula hoop spinning.

Researchers used robotic models to determine that a narrow waist and wide hips provide optimal stability.

Individuals with less curvy bodies can compensate by moving their hips faster and with greater range.

The study, published recently, also helps in understanding how to control spinning objects in other fields.
