Michelle Obama
"I began to prioritize exercise because I realized that my happiness is tied to how I feel about myself. I want my girls to see a mother who takes care of herself, even if that means I have to get up at 4:30 so I can do a workout."

Health quotes from the former First Lady help us get up early.

Cameron Diaz
"The fountain of youth, let's see... I guess it's exercise, healthy diet, lots of water, lots of laughter, lots of sex -- yes, sex, we need that as human beings. It's healthy, it's natural, it's what we are here to do!"

A fresh take on what health means!

Marissa Miller
"Eating smart is all about having an awareness of your body. The most obvious way to do that is by seeing it. So when you're trying to lose weight, spend more time wearing less. I don't think I could eat a plate of nachos naked -- could you?"

Hot clothes lead to a hot body? We love health quotes like this one.

Cher
"Fitness -- if it came in a bottle, everybody would have a great body."

Sadly, you can't buy fitness.

Jennifer Hudson
"The key thing is figuring out what your issues are, and it's really never about the food. You have to be real and honest with yourself. I had to stop and look and ask myself, 'Why do I want this? What is the real reason?' At times, it was comfort food like chocolate. I love chocolate, and I realized it relaxes me, so when you acknowledge what the issue is, you can control it better."

We all need a few health quotes on the importance of doing a deep dive into our emotions.

Michael Jordan
"If you're trying to achieve, there will be roadblocks. I've had them; everybody has had them. But obstacles don't have to stop you. If you run into a wall, don't turn around and give up. Figure out how to climb it, go through it or work around it."

Inspiration from one of the greats.

Tracy Anderson
"In research, the number of muscles in our body keeps going up because [scientists are] starting to look at smooth muscle differently. We need to be connected. Everything needs to be called into action, and our brains -- which remain one of the most mysterious objects in the universe to this day -- have got to participate."

"There are times when I feel lazy and just want to stay in bed all day, but I know that working out is the best way to get those endorphins going, which will make me feel better emotionally and physically."

A reminder that exercise really is the best medicine.

Lance Armstrong
"Pain is temporary. It may last a minute, or an hour, or a day, or a year, but eventually it will subside and something else will take its place. If I quit, however, it lasts forever."
