Being married to the president of the United States is among “the best jobs in the world,” according to first lady Michelle Obama. “We get to work on what we’re passionate about.”

For Obama, that means children’s fitness and nutrition. Her “Let’s Move” campaign not only targets obesity among youth, but also encourages entire families to adopt better health habits.

Obama practices what she preaches when it comes to fitness: She exercises for 90 minutes every day. She often takes her workouts on the road, exercising with schoolchildren at Let’s Move events across the country.

The first lady is equally passionate about healthy eating. She planted the first White House kitchen garden in more than 50 years and regularly invites children to help pick the fruits and vegetables grown there.

She has even been known to recruit young cooks to help prepare nutritious meals using food from the garden.

In June, Obama traveled to the 2015 World Expo in Milan to highlight Let’s Move. In addition to touring the USA Pavilion, where she was greeted by student ambassadors, she participated in a healthy cooking demonstration with local schoolchildren.

Obama is also committed to advancing girls’ education through the Let Girls Learn initiative. In March, she visited Cambodia and urged female students there to finish their education and become role models in their communities.

The first lady also took her education message to London. At the Mulberry School for Girls in June, she encouraged students to set high academic goals.
