Nieky Holzken announced his retirement from professional kickboxing and boxing on Monday via Instagram, ending one of combat sports’ most accomplished careers. The Dutch striker, who amassed over 150 fights and captured 7 world titles in kickboxing, revealed the decision came after extensive reflection on his future in the sport.
“After a lot of reflection, I’ve made one of the hardest decisions of my life. I am stepping away from my active career,” Holzken posted on social media.
Legacy in Kickboxing
Known as “The Natural,” the Dutch striker amassed over 150 fights, seven world titles, and a recorded kickboxing record of approximately 94-16 (with some sources citing ~90-14, 46 KOs).
A four-time GLORY Kickboxing champion, Holzken also competed prominently in ONE Championship and K-1 MAX, and held a 15-1 boxing record with 11 knockouts.
His signature style – devastating left hooks, uppercuts, and precise body shots – made him one of the most feared strikers in combat sports history.
Transition to Coaching
Rather than stepping away from combat sports entirely, Holzken plans to focus on the next phase of his career: developing future champions. The Dutch fighter intends to leverage his extensive experience and technical knowledge to train the next generation of fighters, continuing his involvement in the sport he dominated for so long.
Holzken’s retirement marks the end of an era for kickboxing, removing one of its most consistent and skilled competitors from active competition.
