Now in his 10th season as one of the fitness trainers on NBC's worldwide hit "The Biggest Loser," Harper has become one of the most credible and sought-after motivational experts on television and DVD, in books and in personal appearances.

In addition to his leadership on "The Biggest Loser," Harper is a regular on "The Dr. Oz Show" as a member of Core Team Oz, and his book Are You Ready! was published in 2008. He has made appearances on such shows as "Oprah," "Larry King Live," "Jay Leno" and "Ellen." He has also been featured in magazines such as Oprah Magazine, Men's Health, Entertainment Weekly, and People Magazine. Harper's optimistic outlook, practical advice and gregarious demeanor have earned him fans and followers all over the country.

Harper's new DVD series, the "My Trainer Bob - Inside Out Method" is a raw, high performance, results-centered training program comprised of four DVDs featuring strength, cardio, yoga, and personal training workouts. The DVD series is a challenging integration of mind, body and spiritual fitness that aggressively pushes viewers further than they have ever gone mentally and physically, empowering them with a better body and a better life.

Harper has spent more than a decade in Los Angeles developing his trademark brand of fitness and nutritional integration that leads to lasting lifestyle transformations, and in so doing, he has cultivated a devoted following of clients. Harper's approach is founded upon knowing that quick-fix fitness does not lead to continuing and meaningful changes.

Harper adopts an "inside out" philosophy, in which he builds a relationship with each client. He motivates them to realize their potential and their sense of self-worth, and then helps them to develop habits - and ways of thinking and acting - which enrich and uplift them physically, emotionally and spiritually. His comprehensive approach has led to countless success stories, from top-name celebrities whom he has privately trained, to those who discovered Harper as a group instructor.

He has trained hundreds at a time in stadiums in the Far East, and has been an instructor to trainers themselves, who have absorbed and replicated Harper's energetic and transformative methods with their own clients.

Harper is certified with the American Fitness Training of Athletics and with Aerobics and Fitness Association of America.

Q and A with Bob Harper:
What's your workout routine?
I work out 6 days a week for about 90 minutes. It could be running, interval training, spinning, yoga or just regular weight training. I like to mix it up but mainly I want to get my heart rate up and push myself to new limits.

What healthy foods do you try and eat regularly?
I eat a lot of every kind of fruit out there and eat lots of beans and green veggies. I get my protein from plant-based sources and drink tons of water.

What's the one UNhealthy habit you need to work on?
I need to get more sleep.

What health tip, if any, do you want to share with others?
The one health tip I would tell people is to cut out high processed foods. Your food should basically have a shelf life of no more than 2 weeks. Processed foods are very high in sodium and is bad for your heart and overall health.
