The office of First Lady Michelle Obama is taking credit for moving the nation "towards a new, healthier norm," according to a press release celebrating the four year anniversary of the "Let's Move" initiative.

"This week, First Lady Michelle Obama will kick off a celebration around the fourth anniversary of Let’s Move!, her initiative to ensure that all our children grow up healthy and reach their full potential," reads the release.

Today, we are moving toward a healthier future and this movement is becoming the new norm all across the country. From child care centers through high school, from sun up to sun down the country is moving toward a healthier future.

On this anniversary, Mrs. Obama will be highlighting examples of people, communities, and organizations that are participating in this movement.

To demonstrate the national scope of this movement, the First Lady is encouraging people of all ages, to show her how they move - through their everyday fitness routine, making better food choices, or by moving their community toward that new norm - on Facebook, Twitter, Instagram, Vine, etc. using #LetsMove.

Mrs. Obama launched Let’s Move! on February 9, 2010 to unite the country around our kids’ health and create real support for families to live healthier lives. Since then, parents, business leaders, educators, elected officials, military leaders, chefs, physicians, athletes, childcare providers, community and faith leaders, and kids themselves have stepped up to improve the health of our nation’s children.

Thanks in part to these efforts, our nation is moving towards a new, healthier norm. More Americans now have access to healthy, affordable food closer to home, school health environments are changing, healthier foods are being marketed to kids, and making healthy choices is becoming easier for families. A CDC report released last year showed that obesity among low-income pre-schoolers declined in 19 states over the past couple of years.

The press release also mentions a series of events Michelle Obama will be doing to celebrate "Let's Move," including an interview with Jenna Bush Hager, daughter of George W. Bush, for NBC's Today Show.
