ROAD TO DESTRUCTION Chicago's Beth Horn, 34, has been a gymnast since the age of seven — and weight training since the age of 15, when she had both knees reconstructed. (''I had a great doctor. I have great genetics. I just had to work on the muscles and keep them strong,'' she says. ''They're great.'' Those shoulders aren't bad either.) The 5'8'', 137-lb. personal trainer and Pro Fitness competitor is also the author of the nutrition and fitness book The Natural Way.

CHARACTER DEVELOPMENT ''Venom is perfect for me,'' she says. ''I am sweet and friendly and feminine on the outside, yet I will strike at any given moment.''
