First Lady Wins Ellen's TV Press-Up Challenge

Michelle Obama has triumphed after accepting a press-up challenge from Ellen DeGeneres on the comic's TV talk show.

The 48-year-old easily completed 25 in front of a studio audience and millions of television viewers.

"I thought it wouldn't be good to show up the First Lady so I stopped," quipped DeGeneres after quitting.

"I thought this looks bad that I'm going to beat her. I'm 54 and you're 48."

Mrs Obama also revealed something about life with the US President behind the doors of the White House.

"He (Barack Obama) doesn't pick up his socks," she said in response to a question sent in from a viewer.

"He thinks he's neat but he has people who help him," she told DeGeneres.

"I'm like, 'it's not you that's neat. It's the people who pick up your socks. Those are the neat people'," she said.

Mrs Obama has been in Los Angeles promoting her "Let's Move" campaign to combat childhood obesity in a series of TV appearances.

On Tuesday, she brought food from the White House kitchen garden to show Jay Leno on The Tonight Show.
