Bodybuilder and actor Vittorio “Vito” Pirbazari, who appeared in the Netflix series Dogs of Berlin, has died at age 44. Pirbazari’s friend Said Ibraham was one of the first to confirm his death in an Instagram video post on Tuesday, April 1. Tributes from shocked friends and family have poured in since the announcement, with Ibraham suggesting in his video that Pirbazari may have suffered a heart attack while working out at the gym. On March 30, Pirbazari shared a health update in what would be his last post on Instagram, captioning a selfie: “I haven’t been able to pull much exercise for the last 3 months, but I worked hard on my diet.” He added that he was “trying intervals on the treadmill” but “taking it slowly” because his legs were “not 100% healed yet.” For Pirbazari, the most important thing was to “not give up.” The muscleman also appeared in the German crime series Tatort and was part of a YouTube fitness crew called “Hardgainer.”
