Regular exercise...it’s better than you
You have probably heard it since childhood: exercise
is good for you. Recent studies suggest that this might be even
more true than previously thought. It is common knowledge today
that regular weight bearing exercise (e.g., weight lifting) can
help stay off the bone loss that often accompanies aging, and that
aerobic exercise (any sustained activity that is vigorous enough
to get your heart rate up and cause you to break a sweat) is critical
to cardiovascular health.
Many may have heard that a recent Stanford study
found regular exercise to mitigate some of the impact of poor lifestyle
factors such as smoking and poor diet. A few more of the many recent
- as little as three hours of moderately vigorous exercise per
week can reduce the risk of developing insulin insensitivity syndrome,
a common precursor of diabetes and heart disease, by half (1)
- the immediate pain generated by exercise in people with osteoarthritis
is short lived and is associated with a decrease in osteoarthritic
pain in the long-run(2)
- weight training can stay off and even reverse the muscle mass
loss associated with aging(3)
- a well designed aerobic training program can, in as little as
six months, enable men in their 50's to regain the aerobic power
they enjoyed in their 20's(4).
We’ve seen a surge in such research into aging in the last
decade and the accumulating body of scientific knowledge is pointing
toward this: Most of the degenerative changes we see in people as
they age are not the inevitable result of aging itself, but are
due to disuse, misuse, and abuse of our bodies over time.
There is every reason to believe that most of us have the option
of retaining youthful vigour and optimal health right up to the
very twilight of our lives. Regular exercise may well prove to be
the most important factor in ensuring this. If you do exercise regularly,
congratulations. Perhaps I’ll see you out there when I’m
surfing in Kaui in 50 years.
If you don’t exercise, why not give it another go? Here
are a few guidelines that may help you establish a balanced approach:
- Don’t call it exercise if that word is a turn off. Call
it tending to your physical portfolio, physiquing, buffing, or just
about anything else that has a positive ring to it for you.
- Whatever you choose to do, make it fun. Although working out
often seems difficult at first as your body adjusts to the new demands
being placed on it, if it is fun you’ll stick to it and get
over that initial period of discomfort. Choosing a variety of activities
can help prevent boredom and usually provides a better, well rounded
- Try to do something moderately vigorous each day. Four days a
week is really all that is needed, but doing something daily can
help integrate it into your lifestyle. Even a brisk 30 minute walk
a day can substantially reduce the risk of heart disease.
- Mix aerobic activities, with those that build muscle strength,
such as weight lifting. Alternating days between the two is a good
- Look for hidden opportunities to work it: Taking the stairs rather
than the elevator; walking / biking rather than driving; parking
at the far end of the store lot.
- To increase and maintain flexibility, add in a stretching routine.
This can be done as part of a warm up or cool down for your daily
routine of aerobic and strength building activities, or it can
be done separately, perhaps as part of your preparations for bed.
Stretching is an excellent way to relax after a long day. When
you begin to discover the true joys of stretching, you may want
to try a few weeks of yoga.
