[Narrator:] From the University of California at Davis, this is NewsWatch.
[Andrea Khoo, UC Davis P.E. Instructor:] Nat. sound open demonstrating kick boxing routine.
[Paul Pfotenhauer:] The most popular physical education classes at UC Davis are taught by Andrea Khoo. In fact, they are so popular that hundreds of students are turned away every quarter.
[Paul Pfotenhauer:] Andrea Khoo's purpose in life is to get young people to think about the importance of a total body workout.
[Andrea Khoo:] It is a combination of weight lifting and cardio and the last part — genetics. I always tell the students, I'm going to work with your genetics, not against your genetics.
[Paul Pfotenhauer:] She teaches three classes back-to-back and at the end of the three hours, she's still full of energy. In addition to her brutal workouts, she competes as a bodybuilder and is a freelance fashion designer.
[Paul Pfotenhauer:] More than half her class are students who enroll year after year in her three-phased routine…step aerobics, kick boxing, abs and back. Dave Shira (shy-ra) , a senior mechanical engineering student, is one of those.
[Shira:] Lost about 20 pounds from starting, feel better, look better, more flexibility, more endurance.
[Heather Jackson, Senior, Civil Engineering Major:] There is always something new in her class. She keeps me going…she always finds a new way to kick my butt. I have never felt this strong in my life.
[Sierra Feldmann, Sophmore, Political Science Major:] She's really enthusiastic, she wants you to learn, she wants you to succeed and she knows that you may be beginning, you maybe advance and she'll work with you.
[Paul Pfotenhauer:] Khoo's 9 percent body fat is achieved through a rigorous schedule that focuses on proper nutrition and hard workouts.
[Andrea Khoo:] I'm just very intense.
