The 'Idol Star Athletics Championship', commonly known as the 'ISAC', began in 2010 and has become a tradition for Chuseok and New Year's holidays ever since. Back on Chuseok, the 'ISAC' introduced the brand new genre of women's rhythmic gymnastics, and received great feedback. Supposedly, MBC has decided to try out another new genre for New Year's, and idol groups B.A.P, TEEN TOP, Seventeen, KNK, and ASTRO have begun practicing for the new men's aerobics. 

However, MBC has since denied the reports, saying, "We are currently discussing adding a new team sport. Men's aerobics, as well as badminton and ping pong, are team sports we're considering adding." Although MBC was careful with their words, it seems like men's aerobics may be a possible new category for the 'ISAC' this New Year's. 

Meanwhile, the New Year's special of 'ISAC' will hold its filming on January 16.
