This is the bizarre moment a bikini-clad woman sat on a yoga ball rolls it up and down her client’s back in a public gym.
As one fitness fanatic pumped some iron in Shanghai, China, on January 13, he noticed some people filming.
Popping his head around the corner, there was a woman dressed in a white bikini top and black bottoms sat atop a fluorescent pink Swiss ball rolling back and forth.
Surprisingly, there was another punter lying face down on the floor being used as a human exercise mat for the unorthodox exercise.
The person behind the Instagram account Shanghai Observed explained: “I definitely got a good laugh out of this.
“I’ve never seen anyone film in the gym before so when this guy walked in with a camera and an attractive woman wearing a bikini, it piqued my interest.
“Maybe they were filming a music video because I can’t imagine what health benefits this would have.
“They carried on for at least 20 minutes before leaving.”
