After 26 years, I am still practicing what I preach.

Over the years, Ive covered 22,000 miles.

Far too many times over the next 12 to 15 years, it was brought to my attention that people who followed my exercise guidelines exactly but ignored their diet, their weight and their cigarette smoking had heart attacks at age 55.

According to the Gallup Poll, 24 percent of American adults exercised regularly in 1961, and 50 percent after 1968. The peak was 59 percent in 1984, dropping off to 51 percent last September.

You have to run 75 to 100 miles a week if you expect to break the four-minute mile.

Exercise is a journey, not a destination. It must be continued for the rest of your life. We do not stop exercising because we grow old - we grow old because we stop exercising.
