The 27-year-old reality star's exercise DVDs have been on sale for months now, but we just landed an exclusive, behind-the-scenes interview with the fitness pro who actually choreographed the DVDs and hung out with Kim Kardashian on-set during filming of the best-selling series. Jennifer Galardi, a dancer, trainer and creator of nearly two dozen exercise videos had lots to dish about:

That's Fit: We all want to know Kim's absolute favorite lower-body moves, the ones she does at home and the ones she mastered on the set.

Jennifer Galardi: Kim loves backward lunges and the balancing "T" where she would lift one leg, balance on the other and lower her body until it was in a "T" formation. Some of her favorite body-sculpting moves are also the most popular in many other videos and in fitness classes across the country, the lunge and the traditional squat.

I've never even heard of deep-fried Oreos but I hear Kim Kardashian, star of E!'s Keeping Up with the Kardashians, plans to give them up as part of her New Year's resolution.

Besides swearing off her sinful indulgence, the 27-year-old says she's going on a diet. Don't worry, she won't starve herself. She just wants to eat better.

"I need to start eating responsibly," says the new girlfriend of NFL star Reggie Bush, who reports she gets enough exercise but eats like crap.

Kardashian has no specific diet plans on her radar at the moment.

"I know what's good for me and what isn't," she says. "It's just a matter of making the right choices."

I wanted to share one of the best fitness photos I've taken in my 17 year career. I train a lovely and highly motivated woman Kim, who comes in three times per week. Kim has been training with me for about five weeks and she's already lost 17 pounds; she's dropped down from a size 18 to a 10 as well. Kim is one of the cool folks who doesn't necessarily love exercise, but she does it because she knows it will get her where she wants to be. So far she adores the results she has earned.

Back to the photo. Kim shows her lack of love for training quite often with moans, groans and pleas for mercy. She also makes these amazing faces. I suppose it's all her way to get me to take pity on her and allow her to stop whatever horrendous thing we may be doing at the time. It never works. But the efforts she puts forth that lead to these faces of agony are the same ones that cause her to skip in beaming about her new pants.
