The foundation for my fitness book idea

The Diesel Games - I am Diesel Dad, is the foundation for my fitness routine. Highly intensive but doable for any man or woman. Over 40-50 ideal as this will reverse the aging process!!!! Still, a 20 or 30 something will find it extremely difficult to keep up and perform - like I have for 5 years and counting....at the age of 51.
