Malmberg began before the First World War in Gothenburg with the rings. Through regional successes he soon reached the summit in the Swedish top class. He preferred the Greek - Roman style. International success he could reap only after 1920. At the Olympic Games in 1924 and 1928, he failed at featherweight at the Finn Kalle Anttila and Aleksanteri Toivola and the Estonians Voldemar Väli. But in 1932 he made the Olympic gold medal in the lightweight in Los Angeles, beating even the three -time German champions Eduard Sperling from Dortmund. He was already 38 years old.
Malmberg launched for IS Örgryte Gothenburg and was an independent businessman.
