Vuk's fitness journey began years ago, serving as an outlet to cope with life's challenges. This evolved into a deep passion, leading him to share his "life hack" for a better existence through fitness coaching. With a strong commitment to the Iron Lifestyle, Vuk was encouraged to compete in bodybuilding. He started his contest preparation in 2023 and triumphed at his first competition, the 2023 Santa Cruz Championships, in August. During the event, judge and promoter John Tuman dubbed him "the Serbian Nightmare." Later that year, Vuk secured third place at his inaugural national show. In August 2024, he participated in his third competition and won the coveted IFBB Pro Card.
