The reality star, 33, works out nearly every day, often in the early morning, according to an insider, varying between classes at Barry's Boot Camp and spinning at SoulCycle. "She alternates between different types of workouts for a better result," says the source.
And 10-month-old daughter North often gets in on the action – Kardashian pushes Nori in her stroller on long walks around their Hidden Hills neighborhood. And there's no rest for the weary, even on vacation. When Kardashian took an Easter trip to Santa Barbara, "she kept up with her workouts," says the insider. "She's very focused and dedicated to her routine."
And as the clock is ticking, it's clear that Kardashian's hard work is paying off. Famously criticized for the 50 pounds she gained while pregnant, the star has been steadily shedding the weight through a healthy Atkins-based diet and her commitment to exercise.
Says the insider: "It's obvious she wants to look her best for the wedding. And she looks amazing!"
