"My fitness journey will be a life long journey," Khloe wrote along with a selfie back in February. "Fitness is not about being better than someone else… It's about being better than you used to be. I'm not where I want to be and who knows if I ever will be. But I am healthier than ever and due to my consistent workouts, I am slowly seeing results."
