Nguyen Van Lam, Asian champion bodybuilder in the men's 65kg category, won the world championship in Malaysia on Friday.
Lam's superb performances on Friday morning enabled him to win a field crowded with more than 100 bodybuilders from 45 countries and territories.
Lam had taken the bronze medal at the competition organized by the World Bodybuilding & Physique Sports Federation in the United Arab Emirates (UAE) two years ago.
On Saturday, bodybuilder Pham Van Mach will defend his world championship in the men's 60kg category. Mach won the title in 2009 and 2010.
