Jovette Van Horn adds it's important to take it slow. She keeps her tennis shoes by her desk, and walks stairs and the skywalk system at work. She used to take a break by having a snack. Now she walks, and has more energy because of it. Her desk is lined with pictures. Shots of her family are on one side. On the other are framed pictures of her over the last year.

"I just kind of keep them as a reminder of where I've been, and it shows me where I am not, too," says Van Horn. "I don't get that mindset of, 'Oh, I've got so far to go,' it's, 'Here is where I have been and where am I now."

For Van Horn, fitness is about being healthy. Losing weight is just a bonus. She says she wants to be thin by society's standards, but this time she's exercising for the right reasons.

Exercise specialists say people who don't need to work at being thin, still need to get off the couch. They could be unhealthy and not even know it.
