The 32-year-old told the magazine she wanted to inspire other new mothers who were feeling overwhelmed at the thought of restarting their exercise routines.
'I'm proof that even after having a baby you can look better and sexier than ever,' she told Shape.
Kardashian, mother to 18-month-old Mason, explained that she began exercising as a young girl.
'My family has always been into exercise,' she said. 'My dad [Robert Kardashian] used to tape episodes of Seinfeld and Friends and watch them while he was on the treadmill.'

Now, as a new mother, she has resorted to her old routine of running to get in shape.
She said: 'I tried working out at the gym in our New York City hotel, which was boring, and I took bootcamp classes with Kim, but they're just not for me.'
But running isn't without it's challenges - not least finding the time.

'Know when is the right time for your workout and commit to doing it,' she advised.

'For me, I have to get up at 7am every day, before everyone else, leave Mason in bed with Scott, and go for a run.
'Thirty minutes of cardio is right outside my door.'
Having started eating healthily during pregnancy, Kardashian has kept up the habit.
She now eats lots of fruit and vegetables, ordering healthy side dishes like spinach and carrots in restaurants.
'It wasn't just because it's good for me, I've discovered I really like eating that way,' she explained.
