Girl group Girl's Day's member Minah proved her strength.

In MBC "2014 New Years Special Idol Star Olympics" aired yesterday, Girl's Day and Dal Shabet held their semifinal match.

Minah prepared to push the curling stone, but instead of pushing hers, she tried to push Dal Shabet's stone. So in order to switch the stone, she lifted a stone that was almost 20kg, shocking everyone there.

Even the MCs said, "Even professional players don't even lift that easily."
