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

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

It's easier and more cost effective to maintain good health, than to regain it once it's lost.

If you look at body fat, it seems to increase with age, even though your weight does not. That's a physiological fact of aging, they say. Heck it is. It is an adaptive effect of aging.

I don't criticize weight training - as long as it is not a substitute for aerobic training.

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.

Since then, I have not missed five consecutive days in getting some type of aerobic exercise, mostly jogging.
