Sound Mind, Sound Body: David Kirsch's Ultimate 6 Week Fitness Transformation for Men and Women

When I need to get in shape fast, I know that David's the man. . . . I work out when I want to get toned for a job like a Victoria's Secret fashion show or the Sports Illustrated swimsuit issue. I take care of myself, but if I went to the gym on my own, I'd probably end up doing a little bit on the bicycle and calling it a day . . . but with David, I know I'll get some real results because he'll kick my butt into shape! --Heidi Klum

As a human being, a friend, and a personal trainer, David Kirsch has assisted me with so much. On a daily basis, he helps me free my mind, free my body, and free my spirit. David Kirsch's regime is not just a routine, it's an honoring process. --James King, supermodel

With David Kirsch, I have been working out religiously--and with great fervor, too! I can honestly say I have never felt better about my body, its strength, and its flexibility. The energy I have now is stupendous. People tell me I look fabulous . . . I know I feel fabulous . . . and it just takes commitment and dedication and a workout with David to turn things around. Happy exercising. --Ivana Trump

Let's just say you haven't seen the inside of a gym in, oh, 4 years . . . and that your main source of nutrition is movie-theater popcorn and licorice. And you finally decide this has to change (yes, I'm talking about myself). David Kirsch, the ultimate transformer, can pull you out of this mess. His exercise program is tough, no doubt about it, but it's also fun . . . David does it. David is Goliath. --Linda Wells, editor-in-chief, Allure magazine
