If you're bored with oldfashioned running, or if you feel that it's not a complete workout, you might want to try crunning. It does not mean crying while running. It's actually a cross between crawling (爬行) and running that involves getting down on all fours and moving.
The strange workout, best described as your thighs' (大腿) worst nightmare, was invented by Australian fitness enthusiast Shaun McCarthy. The video of his crunning has been getting much attention online and it has inspired others to take up running on all fours as well. Now crunning is a steadilygrowing sport in Australia.
McCarthy says that crunning is a more complete workout because it involves the upper body as well. “It really works your thighs and shoulders at the same time，” he said, adding that he believes it burns more calories as well. Some fitness experts believe that McCarthy might just be onto something there. According to Kim Baylor, a certified personal trainer, any exercise that involves full body motions leaves the chance to develop a lot of strength.
However, many think crunning is likely to be out of date soon and it might even be harmful if done incorrectly. Fitness coach Kevin Dean said, “We humans are upright; our wrists have different structures than ankles. But a quadruped (四足的) animal would have four of roughly the same joint. As a result, I often see broken noses, bad wrists, and shoulder problems arising from crunning.”
Health experts suggest wearing special gloves to prevent damage to hands while crunning. It's necessary to increase the intensity (强度) of exercise step by step. Crunning may be too much for a beginner and it could be bad for your neck. If it hurts severely, stop immediately and just stick to traditional running.
