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 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 practise 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 .
