According to scientists, an intense tae-bo workout routine caused the upper floors of a 39-story high-rise in Seoul, South Korea to start shaking as if there was an earthquake. Holy shit! *regrets giving away Billy Blanks workout DVD's*
...17 middle-aged people were working out to the pop song "The Power" by Snap on July 5 when their movements set the upper floors of the tower shaking for 10 minutes, according to a report from the Korea JoongAng Daily.
"It just happens to be that the vibration cycle caused by Tae Bo collided with the vertical vibration cycle unique to the building," Chung told the Korea Times. The action amplified the building's vibration and caused the shaking, he said.
Chung was one of six professors from the Architectural Institute of Korea who inspected the building and recreated the Tae Bo exercise.
That's nuts. Although I can't say I'm surprised since one time I jumped really hard in an elevator and it broke. Everyone I was stuck with got piiiiiiiiiiiiiiiiiissed. I'm sure my gas didn't help. Or did it? One lady puked so I think that helped alleviate some of the blame.
Thanks again to comfort eagle, who will swoop down and scoop you up with his talons if the building you're in starts shaking too badly. That or accidentally claw your face off.
