"Tracy said I needed to do something about my fitness as I wasn't getting any younger," Que said in an Asian Tour news release after pocketing a check for $60,000.
"I went on a no meat diet and I started from scratch and it helped me a lot to get my mind off things."
Que said his wife has reminded him to remember the yoga techniques when he spoke to her the night before the final round, and it had helped him to deal with the pressure of the playoff.
"I was doing my breathing coming down the stretch," said Que. "She had taught me how to do it and if I was thinking too much in my mind, she also taught me something else to snap out of it. I did my breathing diligently and it helped."
Que's last two Asian Tour wins came in 2004 and 2008 but were followed by fallow periods -- an error he was determined not to repeat.
"One mistake that I had after winning was that I was full of confidence but I kept missing cuts right away," he said.
"I think my expectations went up but winning doesn't mean you're going to be hitting perfect shots all the time. This time, I'm going to play it like I haven't won anything."
