Georges Rooms began weightlifting in his teen years and quickly made a name for himself in the sport by lifting 121 kg at age 21. Unfortunately, his promising career was interrupted by the First World War in which he served and was taken prisoner-of-war. He made a return to sport soon after the war, joining the Verenigde Krachtmeters club in Gent, winning a club as well as a Flanders championship title. Rooms also occasionally competed in club wrestling tournaments. After a successful run, he left active competition briefly, but made a return to compete at the 1920 Olympic Games held in Antwerpen, at the urging of his contemporaries. There, he won the bronze medal in the lightweight class behind compatriot Louis Williquet of Liège, lifting 230.0 kg. Shortly following the Olympics, Rooms retired from active competition once again, this time for good.
