Can you imagine doing push-ups on razor blades? Well neither can we, but Xie Guanghai a fifty seven year old professor in China’s Henan Province can’t imagine doing them without the blades. He can do 12 push-ups in a row in 40 seconds on the razor sharp blades. He has completed over 1,576,500 pushups in a year. That’s an amazing amount before the razors are added into the equation.
