Current exercise guidelines from the
federal government recommend at least
one hundred fifty minutes per week of
moderate exercise or seventy-five
minutes of vigorous exercise. Not many
of us do that. A new study from Duke
University, appearing in the Journal of
the American Heart Association, found
the most dramatic improvements in
overall risk of death and disease occurred
with a relatively small amount of
exercise, although the more you do the
better the benefits. So, even short
bursts of moderate to vigorous exercise,
under ten minutes, offers the same
benefits—as long as they add up to onehalf
hour per day or longer. Those who
got sixty minutes a day cut their risk of
death by fifty-seven percent, compared
to those with less than twenty minutes.
