Bagam Aygubov, a 66-year-old man, entered the Russian Book of Records after losing 9.3 kg after a five-hour run.
According to Gadin.Net, this was reported by RIA Novosti.
It is said that no one has done such a thing until the man from Dagestan.
“There were times when I lost more than 15 kg in seven or eight hours. "My goal today was 10 kilograms because I wanted to set new records," Aygubov said.
