There's no denying the fact that Kourtney Kardashian is in the best shape of her life, and she wants her fans to know exactly what motivates her to get into the gym every single day.
The Keeping Up With the Kardashians star spilled all about how fitness has helped her through some difficult times this year on her app.
"When I was pregnant with Reign [Disick], I knew that I was going to go hard at working out afterwards. I couldn't wait to feel strong and in shape again," the 36-year-old wrote.
"I didn't know that I would be going through a breakup and just an overall crazy year. Everyone deals with hard times in their lives differently. I'm generally not a nervous person but I get anxious."
