Kardashian West revealed in an exclusive interview with People Magazine that her fitness inspiration is her younger sister Khloe.
"I saw her naked two days ago changing...and I was, 'Oh my God. You are my body icon.' She's never been more on fire," Kardashian West told People.
Kardashian also shared a video on Snapchat running a trail in a sauna suit. After completing the workout she said in another video, "That was so hard today, but Don and I made it back safe."
In her own weight loss journey, Kardashian West revealed that she has trimmed down through the Atkins 40 Plan, a low-carb diet in which she consumes 1,800 calories a day, including lots of fish and turkey.
The 35-year-old mom emphasized that food and fitness go hand-in-hand. "I think dieting is so important to weight loss, whereas, I didn't really ever think that before," she explained.
While her workouts don't include a sauna suit like her sister, Kardashian West says she hits the gym at 6 a.m. before her children even wake up.
