Sweating it out: The 30-year-old star looked all hot and bothered following her workout
Kim has been hitting the gym every day to make sure her body is as stunning as the 20.5 carat ring on her finger.
The reality star, who announced her engagement to NBA star Humphries last month, broadcast her wedding weight loss plan to her fans on Twitter earlier this week.

Along with using the weight loss product that both Kim and sister Khloe endorse, which claims to jump start your metabolism and burn more calories, the bride-to-be has also called on the services of celebrity trainer Gunnar Peterson (who trains Hollywood's hottest stars including Jennifer Lopez and Minka Kelly).
Peterson kicks her famous bottom into shape with squats, lunges and sprints.

Kim has talked openly about her body struggles telling Harper's Bazaar magazine in the U.S. that she constantly has to watch what she eats.
'I'm on a diet. I need to be. I love to eat - Kit Kats or cookies-and-cream ice cream. I need sugar like five times a day,' she revealed.

'I worked out once. I gained like 10 pounds,' she told the magazine in the interview that came out in February.
'All the papers were like, Kim's pregnant! I ate the nuts on the street corner, the hot dogs, the street meat. It was not a joke.'
