Kim Kardashian is trying to get her figure back.

Because let's be honest, she definitely appears thicker these days than the girl we put on our cover five years ago.

"I'm on a mission," Kardashian tells Us Weekly. "I figure, I'm single. Now is the best time to get in shape."

She says that by working out twice a day— treadmill runs in the AM and strength training or Pilates at night— she dropped 6 pounds in 7 days.

"No more sitting at home, eating too much," she says.

We'll see.
