Fit in Your Jeans by Friday DVD, grab one and start working out and join the challenge.
Kim elaborated in her blog how to join the challenge as follows:
“Just take a photo of your Monday jeans look (before the workout) and then another of your Friday jeans look (after the workout) and send them to kimkardashianchallenge@gmail.com to enter to win the grand prize drawing. I’ll be picking out the winner from the entries and the best transformation will win a pair of sexy designer jeans from Kitson hand picked by me!”
