“I was always overweight as a kid,” the Revenge Body with Khloé Kardashian star, 32, says in a preview released by E! “If I was stressed out or sad, I would eat. So I had to learn how to put all my energy into something positive for me, which is how I fell in love with working out. And I really feel like this journey will do the same for you.”
But it won’t be easy! The series teaser shows people who have decided to transform their lives working with some of the top trainers in Hollywood — including Simone De La Rue, Gunnar Peterson and Harley Pasternak — and showing lots of anger, frustration and sadness along the way.
“The first two or three weeks you’re working out so hard, you’re busting your ass. Sometimes you’re not losing weight, you’re gaining weight because you’re gaining muscle,” Kardashian advises in the promo.

Despite the struggles, Kardashian promises the hard work will be worth it in the end.
“It’s not about a weight number, it’s about how you feel,” she says. “It’s personal, for you and your journey. You’re going to start to transform your body and you’re going to have this revenge on this life that you once had that you won’t even want anymore. Let’s make the haters our biggest motivators.”
