Wong, 46, stole the jury's attention by beating the silver and bronze medalists Aung Swee Naing from Myanmar and Panupong Prateep from Thailand respectively in the 90kg category.
He also made a new record when he emerged as the first national athlete to win the gold in the event at the biennial games.
"I'm very excited to be the first body-building athlete in Malaysia to win the gold in the 'light heavy' category, that is, for big-sized athletes.
"I made preparations for six months for this category because the organisers did not offer the super heavyweight event, so I had to bring down my body weight and focus one hundred per cent during training.
Team manager, Abdul Halim Budin said he was satisfied that the body-building squad achieved the target of one gold and one silver at the games.
