Fitness expert, television star and author Bob Harper is one of the most successful fitness and lifestyle experts in the world. His meteoric rise as the heart of NBC's worldwide hit "The Biggest Loser" – now in its 12th season -- has afforded him the incredible platform to exemplify his passion and vigor as one of the most in-demand fitness specialists worldwide. Harper is the brilliant force behind countless success stories of people that have previously given up on helping themselves, or had been written off as helpless by others. The success of the show has led to the creation of Harper's own DVDs, supplements, books, motivational speaking engagements and personal appearances.

Harper was raised on a cattle farm in Nashville, Tenn., before making his way to Los Angeles in pursuit of his dreams. It was a serendipitous meeting with a trainer that motivated Harper to get into the fitness industry. He received a fitness instructor's certification from the American Fitness Training of Athletics Association and the Aerobic and Fitness Association of America. Now a decade later, Harper has developed his trademark brand of fitness and nutritional integration that leads to lasting lifestyle transformations -- becoming an authority on wellness through motivating others by applying his "Inside Out" philosophy.

As a result of Harper's ever-growing popularity as a trusted lifestyle specialist, Quaker Oats has recently enlisted Harper as its lifestyle coach and advocate for living a healthier everyday life. Harper launched his newest DVD, Ultimate Cardio Body, on Feb 8, 2011. The DVD features two extreme workouts: the "Extreme Cardio Challenge" and the "10-Minute Glute Challenge."

Harper launched his newest endeavor, Bob Harper's Smart Success, in April 2011. The launch of this line of supplements initially includes Bob Harper's Smart Weight Loss, Bob Harper's Smart Weight Loss Starter Kit and Bob Harper's Smart 7-Day Cleanse.

With personal appearances ranging from "The Oprah Winfrey Show," "Larry King Live," "The Tonight Show with Jay Leno" and "The Ellen DeGeneres Show," to being a regular on the Oprah Winfreyapproved show "The Dr. Oz Show" as a member of Core Team Oz, Harper's optimistic outlook is unmatched. His features in magazines such as O Magazine, Men's Health, Entertainment Weekly and People Magazine, have successfully mirrored what his fans and followers around the country crave: Harper's motivation and inspiration to take charge of one's life.

Harper currently resides in Los Angeles with his dog, Karl, a Havanese mix. He still regularly teaches classes in LA, and releases free weekly online workout challenges for his fans.
