Harinck started training in judo and wrestling at 8 years of age. He ended up giving up on judo, after he wasn’t allowed to advance to the rank of black belt, due to his youth. Outside of martial arts, he partook in football, motorcross and Shooting. While working on a cruise ship he met a French sailor who was also a national champion of Savate. The sailor began training Harinck in the discipline, alongside others. Harinck continued practicing Savate after arriving in South Africa. He later took up boxing after he returned to the Netherlands and also started teaching Savate in Holland. While serving in the military as a teenager, Harinck started boxing at the competitive level. At the age of seventeen he worked as a bouncer at a local Club and began a partnership with Jan Stapper, a Kyokushin instructor.

His global journeys continued after he moved to Japan where he received the Uchi-deshi instruction under numerous masters in Tokyo, Nagano and Yokohama. He also received judo and traditional jujutsu instruction from Tokyo police department. He also spent plenty of time in Taiwan, where he entered to train Chinese Kenpo in addition to karate. Eventually he traveled to Thailand where he received the rank of the grand master in Muay Thai as one of the first foreigners ever.
