With all the technology available to kids today, it can be difficult to get them to exercise. Most modern-day children would much rather sit around playing games on their iPads than go outside and exercise, which means that adults have had to get creative in trying to incentivize them to stay active.

Zhang Pengfei, a headmaster at Xi Guan Primary School in northern China, has come up with a unique way to get the students at his school to stay active through dance. Each day, during the 30 minute recess break, Pengfei leads his students in a choreographed dance called “guibu,” which means “ghost steps.”

Video of Pengfei dancing with his students has quickly gone viral, being viewed over 500,000 times! He introduced his dance program back in October, and he said that it has been extremely successful so far. The principal added that it has been particularly successful in getting students off of their phones for thirty minutes each day.

“Now the students aren’t constantly on their phones,” he said. “I sometimes catch them watching different dance routine videos and learning new moves.”

China actually has a law that mandates students to perform a workout in school each day. Most schools have their students do traditional broadcast calisthenics, which consist of modified versions of exercises used by Japanese soldiers during World War II, but Pengfei thinks that this is too boring for modern-day kids.

“I wanted to introduce the [shuffle] dance,” he said, “because the students and [teachers] had no interest at all in the broadcast calisthenics.”
