Girl group 2NE1's member Dara posted a picture of herself working out to prepare for her concert.

Yesterday, Dara posted on her Twitter, "Diamond sit-ups whenever I can during concert rehearsal! Go go," along with a picture.

In the picture, Dara was in a blue shirt and ripped jeans. She made a diamond with her legs sitting down and was doing sit-ups.

Internet users who saw this commented, "Is she building abs?," "So excited for the concert," etc.

2NE1 will be holding a concert in Seoul on March 1 and 2.
