1. The Atkins Diet: "I believe in diets or I will eat anything," Kim previously told E! News. "When I really need to kick it up, then I'll do low carbs, like Atkins diet. And then I think it's just trying to stay consistent, changing the way you eat. Especially after having a baby, it's really hard. Your body totally changes. And I think you have to work out." The low-carb diet, which she famously turned to after giving birth to North West, focuses on lean proteins and healthy fats, such as avocados and nuts.

3. Personal Trainers: Kardashian has worked with two famous celeb trainers in recent years, Tracy Anderson and Gunnar Peterson. While Kim turned to Tracy to whip her back into shape post-baby, she is also a longtime client of Gunnar, who is currently working with her sister Khloe Kardashian and brother Rob Kardashian. Perhaps, Kim might join in on one of her siblings' sweat sessions soon.
