Kim has always been known for her curves, but it wasn't until she started working out with bodybuilder Melissa Alcantara that she achieved her best body ever. "I've been working out really hardcore with a bodybuilder for one year. September is our one-year anniversary," Kim told E! News in 2018, via People. Kim lifts "heavy weights," according to her trainer who told Women's Health that 85% of their training is done with weights and just 15% is cardio. 

Kim works out every day. "I work out about an hour-and-a-half every single day," she told E! News. She added to Vogue that she sleeps for just five hours, waking up at 5:30 am to hit the gym. 

Kim doesn't make excuses when it comes to her workouts. "Just like anybody else, there are days where Kim's not really feeling it, but she will do it," her trainer told People in 2020. "Then there are a lot of days when she's killing it! She never questions the stuff that I make her do, she's just like, 'Okay,' and I love that."

Instead of running for miles on the treadmill, Kim relies on short and fast sprints. "Been sprinting every day!" she wrote in one of her Instagram Stories in 2021. "I've been seeing changes!"

Kim's diet was once heavily meat-based, but she has been gravitating toward plant-based living for the past few years. "My 40s are about being Team Me. I'm going to eat well," she told Vogue. "Plant based and two workouts a day for 30 days to get our mind and body right this year!" she wrote in a January 2021 Instagram post.

Kim workout preps to make her mornings easier. "I will lay my clothes out the night before so when I sleep in, I'll wake up at 5.53[am] instead of 5.45, and I just know my outfit is there," she said. "I have a toothbrush and my toothpaste all ready to go, laid out by my sink. I just have to brush my teeth and go to the gym."

"My trainer Mel always says that before and after you train, you should eat simple carbs, like sweet potatoes, and small amounts of fat and protein, like chicken. You should also have veggies with your meals, since you need them to help effectively break down and absorb your protein, fat, and carbs," she wrote on her app in 2018, according to Harper's Bazaar.

Kim is also into LISS workouts. "Two days out of the week we'll do steady-state cardio," Alcantara explained to WH, "so just walking at a steady pace on the treadmill for usually around 20 minutes. Nothing getting the heart rate too high."

Kim eats clean. "I want her to eat real food that's cooked every day," Alcantara told People. "Most likely if it comes out of a box, it's not going to be good for you."

"When I work with Kim, we like to set goals that we can feel good about reaching," Alcantara explained to Women's Health. "Once we have a goal set, we write it down. I've found that helps hold you accountable. And, it feels amazing when you do finally reach your goal!" "Rather than identify six or seven goals, select and focus on one simple thing you can change today. For instance, identify a single thing related to your diet, such as cutting out sugary drinks and increasing your water intake. If you are someone who drinks multiple sodas daily, you can lose upward of 10 pounds a year by reducing your intake by one soda per day, even if you change nothing else. This is a perfect example of creating success for yourself by just changing one thing," says the Mayo Clinic.
