Malaysian actor Zul Ariffin is showing full dedication to his role in the upcoming film The Furious.

The 38-year-old actor took to Instagram to share with fans his fitness journey in preparation for the role.

He revealed that he has been working out and watching his diet over the past two months to get ripped.

And ripped he became.

Zul shared a photo of himself flaunting his toned body and six-pack abs, which had garnered over 24,000 likes at press time.

But all these sacrifices came at a price, said Zul.

"2 blackouts. 1 nosebleed. And a whole load of migraines and dizziness, low carbs, low sugar, semua low la! and still 2, 3 hrs of training daily," the actor explained in the caption, adding that his two-month training resulted in 20kg weight loss. He now weighs 81kg.

"It wasn’t easy, in fact it has been one of the biggest challenges I’ve taken on to date," he said, adding that the last time he attempted a fitness challenge was nine years ago, during which he lost 12kg.

"I said I’d do it, honestly, not fully confident I really could but sometimes you just gotta grit your teeth and say LET’S GO!!" the Sangkar actor said.

Malaysian celebs and fans applauded Zul's tenacity and left words of encouragement in the comments section.

Content creator Fehim Hodzic said: "What a transformation sir! Inspirational to see these type of posts. Huge respect."
