Roy "Reg" Park (7 June 1928 – 22 November 2007) was an English bodybuilder, businessman, and actor. His first title was Mr Britain in 1946. He then won the Mr Universe in 1951, 1958 and 1965. He also starred in five films, four featured as Hercules and in one, Hercules in the Haunted World (1961), he co-starred with Christopher Lee. Besides his own career and titles, he is probably best known as an idol and mentor to Arnold Schwarzenegger.
With his wife Mareon of 55 years at home and children Jeunesse and Jon Jon by his side, Park died on 22 November 2007 in his home in South Africa, after an eight-month battle with metastatic melanoma (a form of skin cancer). Park's legacy is continued by his son Jon Jon Park, a personal trainer and former Olympic swimmer. Reg Park raised and trained Jon Jon in South Africa. Today Jon Jon Park is the owner of the Legacy Gym, a popular gymnasium in West Los Angeles. Reg's daughter, Jeunesse, founded Food & Trees for Africa, a non profit that changed thousands of lives and landscapes.
Famous for his mass and strength, Reg Park was an early influence and lifelong mentor to champion bodybuilder Arnold Schwarzenegger. Schwarzenegger said that he was inspired to become a bodybuilder after seeing Park. For three years in the 1960s Schwarzenegger was trained by Wag Bennett in his gym in the East End of London, and it was there where he met his idol Reg Park. Bonus footage from the DVD release of the classic documentary film Pumping Iron (1977) features Park mentoring Schwarzenegger. Park can also be heard performing the Master of Ceremonies duties in the Mr. Universe and Mr. Olympia contests featured in the film proper.
