I have not missed a day from work because of illness since 1956.

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.

Exercise can't counteract the damage being done to your body while you continue to smoke. What exercise can do is help you kick the habit.

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

I think investments in general related to the exercise industry are going to be good for a long time.

The reason I exercise is for the quality of life I enjoy.

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.
