Received this e-mail from Jerry at RunningTough.com and I'd like to know
what the group thinks of his opinion. I personally think, to some extent,
he's wrong.

Subject: Why Weightlifting Bad for Runners
Dear Tom,
Hi, Jerry Hopkins here from RunningTough.com.
Strengthening the muscles is becoming more and more
popular among runners.
Several training programs for runners now include some
form of weight lifting.
Weight lifting is good. But, it really isn't for runners.
First of all, a lot of runners don't like weight lifting.
And, for good reason.
The weight lifting exercises they are doing, make them
feel tired, and their
muscles feel like they tighten up.
Several women runners that I have talked to in the past,
don't want to lift
weights for fear of "bulking up". A lot of women don't
want bulging leg muscles.
Most of the weight training exercises come from the world
of body building, and
are isolation type weight training exercises. There are
several problems with
this.
Isolation type weight lifting exercises don't strengthen
the joints. The reason
is that since isolation exercises isolate a muscle, it
also isolates the
connective tissues from the exercise. Hence, your
connective tissues become weak,
while your muscle becomes stronger. This creates an
imbalance, where the muscle
can and will move more weight than the connective tissue
can handle, and this can
create an injury to the connective tissue.
This is one reason why some weight lifters bandage their
joints, to protect them.
This is a bad thing to do because it is not strengthening
the joint. Weight
lifting can lead to your joints hurting. Ask some guys
around the gym who have
been weight lifting for a number of years and ask them if
their joints hurt. You
might be surprised by how many people say yes.
Body builders want to build size for individual muscles.
Isolation exercises are
used by body builders who are concerned with muscle size.
The exercises are
designed for them. This is so that they can stand in front
of judges who judge
them on muscle size, shape, and looks. This is fine for a
body builder, or people
who want to improve their looks. However, for an athlete,
like a runner,
isolation weight lifting isn't an ideal exercise.
Isolation exercises don't teach
your muscle groups to work together. And, they don't
involve connective tissue.
This is how the human body is designed to work, your
muscles working together.
You run with your whole body, not individual parts.
I hope this email has been informative for you! Don't
forget, more emails are on
their way. In fact, you should be receiving your next
email on "Properly
Preparing to Run Outside (Winter, Part I)" shortly.
Thanks,
