Jaroslav Tůma devoted himself to martial arts during his university technical studies. His desire to express himself other than in words later led him to Argentine tango which he began studying in 2004.
He, along with Marianna Arzumanova, represents the teaching method of Rodolf Dinzel's study of tango in Prague. In 2011, they joined forces and organized acting courses according to the principles of KS Stanislavský, on which the Marianna Arzumanová Theater stands today.
