A China-based Xi Sui Jing kung fu practitioner has lifted and swung 80 kilograms worth of bricks with his testicles.
The 48-year-old Zhao Zhenhua, from Henan province, managed to lift the brick pile that was tied on with a rope and swung it back and forth 300 times, the Daily Express reported.
Eyewitness Shaiming Liao, 37, said that it was an eye-watering display as he counted over 300 swings of his hips and he didn't seem to be in any difficulty as he lowered it down.
Liao added that it has been suggested by many that people who followed this style of kung fu could improve the quality of their lives.
The demonstration took place at a kung fu training centre in the city of Zhengzhou in Central China's Henan Province.
