Inmates at a prison in central Philippines have found a new form of exercise and a way to express themselves, through dance.
Every morning, hundreds of prisoners at the Cebu Provincial Detention and Rehabilitation Centre flex their muscles in morning exercises to the tune of 1980's and 90's pop hits.
The routines have earned the inmates millions of fans worldwide after videos of them dancing were posted on the internet video site, YouTube.
Byron Garcia, a Cebu provincial government Security Adviser, who posted the videos on the Internet, said the dancing originally developed as an form of exercise for the inmates.
But Garcia said there are other benefits of the program.
"All those bad thoughts about being here inside, they almost forgot about it. Loneliness for one was eliminated," said Garcia.
In the two weeks since being posted, one of the "performances", a dance to Michael Jackson's "Thriller", has attracted over 3 million hits already.
Other postings showed the inmates dancing to hits such as Queen's "Radio Gaga" and several tunes from the movie "Sister Act".
In one of the "Sister Act" routines, some of the male inmates even wear nuns' habits.
