One thing that I've learned from male role models is that they don't hesitate to invest in themselves, with the view that, if I'm healthy and happy, I'm going to be a better support to my spouse and children. And I've found that to be the case: Once my kids were settled, the next thing I did was take care of my own health and sanity. And made sure that I was exercising and felt good about myself. I'd bring that energy to everything else that I did, the career, relationship, on and on and on.

That's where you just have to get creative. There are all these trampoline parks and there's bowling and there's roller skating.

Throughout my life, I've learned to make choices that make me happy and make sense for me. Even my husband is happier when I'm happy.

People want to feel hopeful.

We have had with Barack Obama some just amazing experiences traveling abroad, being able to introduce our children to the world.... I'm also humbled by the response and the receptiveness, not just here in America, but around the world. There's a part of that warmth and enthusiasm and hope that is surprising and humbling.

Together, we can help make sure that every family that walks into a restaurant can make an easy, healthy choice.

I'm varying my workouts so it's not just cardio but also includes moves to maintain my flexibility.
