Maj. Donald Bigham, U.S. Army strength coach at the U.S. Army Physical Fitness School set the world record in his weight class Friday at USA Powerlifting Arnold Sports Festival at the RAW Challenge.

Bigham squatted 257.5 kilograms, or 567.7 lbs., in the Masters 83 kg. weight class beating the old world record of 255 kg.

Bigham said he it felt "Unreal to know I am blessed to be the best in the world at the present," and that he "definitely has more in the tank and will reflect that at the world championships this summer."

In October he took two gold medals at the 2015 RAW Nationals in Scranton, Pennsylvania even though he had knee injury.

The medals in that contest qualified him for the Arnold Sports Festival in Columbus, Ohio.
