First Lady Michelle Obama is a woman of many talents. The wife of 44th and incumbent President Barack Obama flaunted her forehand in her first visit to the U.S. Open on Friday.

Michelle visited the U.S. Open at New York's Flushing Meadows to promote her Let's Move campaign which seeks to end childhood obesity in the United States. She also praised the U.S. Tennis Association's efforts to build kid-sized courts around the country and recruit more youngsters to the game.

Clad in white sporty top and black pants, Michelle played kid-sized doubles against Serena Williams, clocked a 55-mph serve and even did some hula-hooping, reports the Associated Press.

Addressing local youngsters, Obama said that she didn't play tennis until after law school as they were very few tennis courts near her Chicago home. She warned the young crowd that she was not about to serve at 135 mph, Roger Federer style, according to Politico.

It's the kind of sport that you just develop a passion for. I'm not really good or anything like that. That's the beauty of tennis, she said. You don't have to be good to enjoy it. I love the game, and my skills are very questionable.

She also joined the kids in a tennis video game, table tennis and other activities to encourage the young crowd about the sport.

The First Lady also got to hang out with some of the tennis greats like James Blake, Katrina Adams and even Billie Jean King, who sat behind the First Lady as they took in a match later in the day.

While extolling the values of tennis as an exercise, Michelle said that she introduced her children to tennis quite early.

That's one of the reasons why I introduced the sport to my kids early on, because it's great for kids because it gets you moving, she said.

She hopes to keep playing tennis even in her 90s.

It's a sport you can do forever, Obama said.
