What kind of sports impressed you most during your childhood? Maybe racing around the playground or skipping rope for hours would bring you pleasure. At that time you weren’t thinking of fitness, you were just thinking of entertainment. But in this age of high-tech home equipment and underused gym memberships, the simple joy of jumping rope has been forgotten. I think rediscovering it probably will give you a total-body exercise.
Although considered an excellent form of exercise, jumping rope has never received widespread acceptance because of two 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 in order to achieve a beneficial physical effect. Second, many regard it as somewhat boring and overly repetitive —not as something fun or enjoyable.
As a matter of fact, jumping rope can be great fun as long as you find a proper way to practise it. Instead of doing the usual two-foot bounce(跳) over and over again, players 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 .
Nowadays researchers are discovering that jumping rope also prepares the brain for learning . It is an exercise allowing both brain hemispheres（半球）to perform equallyto 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.
