Oh boy, there is a word for it. It is the exercise for the millions of people who leak when they laugh, sneeze, cough or Zumba. It’s called the Kegel exercise. It was first described in 1948 by Arnold Kegel according to Wikipedia.
Kegel exercises strengthen the pelvic floor and are the #1 treatment for bladder leakage. And these exercises can cause particular facial expressions: the Kegel Face.
There are several ways to exercise. One of them is a personal device guided with an app from the health brand PeriCoach. In their latest campaign they ask the public to share a picture on Facebook, Twitter or Instagram with their Kegel Face and the hashtag #kegelface.
For those who want to start training: you don’t need muscles as strong as this. (h/t Tom)
Earlier this year the brand came up with another light-hearted take on the awkward problem: Leakers Anonymous (see below).
