Cirkunov won junior nationals in judo in 2003, Greco-Roman wrestling national championship in 2005 and national championships in freestyle wrestling in 2005 and 2006.[5] After winning the latter championship, Cirkunov became a Canadian citizen.[5][6] After graduating from high school Cirkunov found Brazilian jiu-jitsu, briefly relocating to Las Vegas to train but returned to Canada to open his own gym.[5] In 2008, Cirkunov won the black belt super heavy division at the Pan No-Gi Jiu-Jitsu Championship.[7] After the unsuccessful venture as a gym owner, he started training at an Xtreme Couture satellite gym in Etobicoke.[5]
