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 member-ships, the simple joy of jumping rope has been
forgotten. Rediscove ring' it will give you a total-body exercise you can find.
Although considered as an excellent form of exercise, jumping rope has never gained widespread
acceptance because of two funda mental reasons. First, most people recognize jumping rope as an ex-cellent
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 hemi- spheres 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.
