Remember how great exercise was when you were a little kid?Back then, racing around the
playground or skipping rope for hours, you weren't thinking fitness, you were thinking entertainment.
But in this age of high-tech home equipment and underused gym memberships, the simple joy of
jumping rope has been forgotten.Rediscovering it will give you a total-body exercise you can find.
Although considered an excellent form of exercise, jumping rope has never gained widespread
acceptance because of two fundamental reasons.First, most people recognize jumping rope as an
excellent form of cardiovascular (心血管的) exercise, but they also believe that it is simply too
difficult.In other words, they don't think they'll be able to continue jumping for the near 20 minutes
that it takes to achieve a beneficial physical outcome.Second, many view it as somewhat boring and
overly repetitive-not as something fun or enjoyable.
As a matter of fact, jumping rope can be great fun if you find a proper way to practice it.Instead
of doing the usual two－foot bounce over and over again, people good at rope－jumping often change
their pattern every 10 or 20 jumps.A single bounce, a double－bounce, a skip, a knee－up, side swings
as well as a variety of other easy－to－learn free－style rope－jumping.
Now researchers are learning that jumping rope also prepares the brain for learning.It is an exercise
allowing both brain hemispheres to perform in parallel to each other.In short, jumping rope can be a
life－long activity requiring little equipment, time and space, yet leading to a much healthier life.
