Michelle Obama to celebrate Let's Move! with jam-packed tour

Michelle Obama is hitting the road to celebrate the third anniversary of her anti-childhood obesity campaign, Let's Move!

The celebration will include stops on "The Late Show with Jimmy Fallon," "Good Morning America" and "The Dr. Oz Show" along with a two-day, nation-wide tour that will include a major announcement about bringing physical activity back to schools, according to the White House, which released the jam-packed schedule on Wednesday.

Obama will also hit the social media circuit with a Google Plus hangout and answering questions via Twitter.

Obama's interview with Fallon will air this Friday. No word if she'll challenge him to another fitness competition, which happened the last time she appeared. Fallon came to the White House for challenge, which include a tug-of-rope contest and a potato sack race. The first lady won.

She also will sit down with ABC's Robin Roberts, who just returned to work after recovering from surgery due to a rare blood disorder, on "GMA" on Tuesday.

As part of her national tour, the first lady will make stops at elementary schools and business across the country.

Rachael Ray will join Obama in Clinton, Miss., on Wednesday, where the two will highlight healthy school lunches. 

On Thursday, the first lady will return to home town of Chicago where she'll make her announcement on physical activities in schools. She'll be joined by Mayor Rahm Emanuel, Education Secretary Arne Duncan, Dominique Dawes, Gabby Douglas, Serena Williams and others for the event.

She'll then head to Springfield, Mo., to visit a Walmart store that is stocking healthier food options.

Her Google Plus hangout will be on Monday, March 4, and will be moderated by Kelly Ripa. On Wednesday, March 6, she'll answer questions via Twitter using her @FLOTUS account.
