Sifu Slim


Sifu Slim (Henry Kreuter) is an author, wellness educator/speaker, lifelong amateur athlete, and leading proponent of “intentional physical activity.” Sifu has developed easy-to-follow programs to empower everyone to achieve more healthful lifestyles and an instinctive wellness mindset. Inspired by legendary fitness icon Jack LaLanne, Sifu has made it his life’s mission to promote “maintenance fitness,” which makes physical activity both recreational and joyful, and a routine part of our daily lives.

“The typical fitness guy has bulging biceps,” he jokes, “I have bulging perseverance and the proof is more than 13,000 days of physical activity. I started back in 1967 following TV-show host Jack LaLanne and have continued to keep wellness as the driving force in my life."

Smashwords Interview

What sets this book apart?
What sets this book apart is how it goes deep to reveal how these incredible athletes were able to overcome significant challenges, become mentored by family, friends, or coaches, and find success in their athleticism and happiness in life after the days of elite level competition.
What athlete's story moved you the most?
That question is impossible to answer. Each athlete moved me in a different way. The most amazing story is probably Charley French since he is still a world class athlete at age 88. When I asked Charley if he was going to donate his body to science, he responded, "If anyone wants it, they can have it."

"The concept is provocative. It is somehow counterintuitive to think of great athletes becoming unfit in old age. The recent suit brought against the NFL by former players indicates the fitness and health can erode all too quickly. The aging pursuers of fitness featured in 'The Aging Athlete' are the exceptions. We can learn from their own stories of perseverance." Tom Jones, Author, 40plussports
