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

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

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.

There are six components of wellness: proper weight and diet, proper exercise, breaking the smoking habit, control of alcohol, stress management and periodic exams.

Over the years, Ive covered 22,000 miles.

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

[Walking's] overwhelming advantage is that it can be done by anyone, anytime, anywhere-and it doesn't even look like exercise.
