     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.
