That doesn't mean they aren't still working on their own transformations as well.
When I met the incredible trainer couple Chris and Heidi Powell a couple of weeks ago (you know them from the hit TV show Extreme Weight Loss), I was immediately impressed by their energy, warmth, and authenticity.
But when we started talking about their story, how they met, and what they overcame before they ever became famous, I was really impressed.
I know it's easy to make up stories about how perfect the people we see on TV are -- but the truth is they are human just like us.
And they have powerful wisdom to share when given the opportunity to tell their stories.
