She always puts exercise first.
In an interview with NPR, Obama family trainer Cornell McClellan said that Michelle isn’t one to skip the gym. Ever. “One of the things that I noticed from them and from herself initially is that this was something that was important and that she prioritized and found a way to fit it in,” he said. “And I remember that when I was working with her all those many years ago, you know, she would be in the gym sometimes at 4:30, 5 o’clock in the morning.”
That’s dedication.
