Do IOI succeed at dancing twice as fast to 'Whatta Man'?

The lovely girls of IOI were guests on the August 31 episode of 'Weekly Idol,' on which they took on the twice sped up dance challenge with their latest hit single "Whatta Man." 

Naturally, the MCs were concerned about Kim So Hye, the member who is known to dance with two left feet. However, the other members assured the MCs, saying, "So Hye really tried her best."

Though she stumbled a bit at first, So Hye quickly matched up with the rest of the members, completing the sped up version of "Whatta Man" like a true pro. 

Great work, ladies!
