A good workout leaves you feeling the burn, but a parkour-style stunt in China could have wound up sparking disaster — and ultimately part of a mega-city blacked out.

It began Sunday night in Chengdu, the central Chinese capital of Sichuan Province, when a 22-year-old man climbed an electric pole to do sit-ups. His gym was too crowded? A search for extra "energy"? A gut instinct to gain celebrity status? Well, no word on the motivation...

The ambitious climber-cruncher finally descended, uninjured. Still, for extra precaution, the local electric company cut power to tens of thousands in Chengdu, with a population of over 16.3 million.

A video of the incident quickly spread on the Chinese social media site Weibo. In the clip (which has so far garnered more than 1.7 million views), the unnamed man can be seen suspended about 10 meters above the ground, feet holding on to the electric pole.

"I was annoyed because we had no electricity, and when I watched the news and found out why I felt annoyed and amused at the same time," said one Weibo user, as reported in Shine.
