Scientist: Tae Bo workout sent skyscraper shaking
Seventeen people performing a vigorous Tae Bo workout caused tremors that forced the evacuation of a South Korean skyscraper earlier this month, the building's owners say.
Prime Group, owner of the 39-story TechnoMart commercial-residential high-rise in Seoul, said 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.
Scientists recreated the event in the 12th floor gym, according to a report in the Korea Times.
“We observed the vibrometer while performing the same kind of aerobic exercise that was performed at the time of the shaking which occurred on July 5. We noticed that the shaking was felt in the upper floors while the exercise was being performed while no other place showed signs of tremor,” Chung Lan, a professor of architectural engineering at Dankook University, told the Korea Times.
“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.
Tae Bo is a mixture of boxing and tae kwon do.

Lol lol lol People will clammer to work in that building. It's gonna shake, rattle, and roll!
GREAT WORKOUT!
I did free weights for chest and back today at the gym. I have an injured knee, and at one point a little old lady told me, "pick up the pace!"
Sign her up as your new trainer. lol You know your not cutting it when the little ole lady approaches.
It was Chuck Norris' mom!
Betty White??
Who gives a crap.
Those had to have been some extremely FAT Koreans!
Sorry for the rush Joey. My geritol pills get me going and going and going. As slow as you were today maybe you should start taking geritol daily. Put some oomph in your workout.
I hear tell that prunes provide the same effect for you elderly folk as well. 😛
Betty White is all over the place.
OK. I'll try prunes.
dang,the same fat to loocy loo!
Ah, harmonic resonance...how you show up during the most inconvenient times...
Why won't my sarcastic comment post? Now I have to play the game of "which word does CNN find offensive?"
This is horrible! Why is CNN giving ideas to the terrorists on how to bring down a building?
You can't say "skyscr4per"? Why?
Now that's a silly word to call offensive – cr4p That's offensive to five year olds, maybe
Because it scares us down here.
Prunes aren't on my Atkins diet.
I've decided to go for Hadacol.
And somewhere out there, the members of early nineties group Snap! are woo hooing that people might flock to iTunes for people wanting to shake rattle and roll their own buildings.
Was Chuck Norris the instructor?
cnn needs a "like" button
No, if he was, the buidling would have fallen down
lol
He was too busy doing Tae Bo on your mom
No he wasn't, it said "middle-aged people"
Duh who else could have done this?
