Mrs. Obama explained her “Get Moving” initiative in an interview broadcast Wednesday on NBC’s “Today” show.
The exercise program is part of a broader campaign the first lady has been pushing for the past three years, including pleas for healthier eating habits.
Mrs. Obama visited Mississippi earlier this year, taking her anti-childhood obesity campaign on the road.
At an elementary school near Jackson, she cited new research showing childhood obesity rates among elementary school pupils in the state had declined by 13.3 percent between 2005 and 2011. She said that “what’s happening here in Mississippi is really what ‘Let’s Move’ is all about.”
