Debbie Siebers has been working in the fitness and training business for over 20 years. As a certified member of the AFAA (Aerobics and Fitness Association of America), the world's largest fitness education association, she has developed and perfected numerous proprietary routines for her clients so they can attack the common trouble spots.

She got her initial experience in personal training working for Body-by-Jake, a pioneer in popularizing personal fitness in the entertainment community. She has also worked as a trainer at Crunch, Powerhouse, Meridian Sports Club, Todd Tramp's Body Sculpting Gym, and the Peninsula chain of luxury hotels.

Debbie has been featured on numerous television programs including Fit TV's health and fitness show "Fitting It In," "Body-by-Jake" exercise segments, as well as on CNN, E! Entertainment Television, and various broadcast network TV stations. 

In 1998, she met Carl Daikeler through a mutual friend, and that led to the creation of the "Thin Thighs Guaranteed!" video for Beachbody.com. The popularity of that video led to additional research with Beachbody into ways one can get better results in less time. The result was "Slim in 6." This was followed by the "Slim Series" and the role of Fitness Advisor on the FOX seires "The Swan."
