Tired of Running？ You May Want To Give “Crunning” A Try！

劉陽(yáng)

Every few years comes a fitness development that has people scratching their heads in amazement. “Crunning” will probably be one of them. In case you are wondering， the “c” stands for “crawling”. Yes， thats right， the new sport makes two-legged humans run on all fours！

The strange idea is the clever idea of Melbourne person Shaun McCarthy. The 34-year-old is sure that it will completely change fitness as we know it. According to the sports fans， “The only thing that crunnings changed about fitness... is that its changed everything about fitness.”

Mccarthy has no scientific evidence to prove that crunning is more helpful than traditional two-legged running. However， he believes it is a more effective way to exercise because it puts an exercise on the shoulders and arms， providing a complete body workout. Mccarthy also says crunning seems to tire him out more. He therefore concludes that the different exercise is a bigger calorie burner than normal running.

While experts generally agree that crunning may provide a better workout， many are not sure if it is the right exercise for humans. Fitness coach Kevin Dean says we are not built to be on all fours and our wrists are therefore not as strong as our ankles. He believes crunning， which he calls a fashion， could result in bad wrist and shoulder injuries， not to mention broken noses.

But McCarthy is not worried. Since the release of his crunning video a few weeks ago， many Melbourne people have been seen moving slowly around on all fours. As it turns out they are not the only ones. In the Chinese city of Zhengzhou， crawling， a much slower version of crunning， has been a favorite activity for many years. According to some fans， the light exercise that is believed to date back two thousand years to the Han Dynasty， is good for curing back and spine ailments.

Ready to give crunning a try？ Then Mccarthy suggests buying some good shoes， hardy gloves and most important of all， a face mask！
