We're not sure what Manny Pacquiao's secret weapon is. Maybe it's his snakebite speed, his rock-hard muscles or his indefatigable conditioning. But one thing's for sure. At this level, it often comes down to mental strength.

You gotta want it. And from what we understand, when he gets into the ring against Shane Mosley at the MGM Grand Garden Arena tomorrow, he's going to want it. Bad.

Turns out that his other trainer, wife Maria Geraldine “Jinkee” Pacquiao, shuts down the sex days, even weeks, before a fight:

“No sex … before a fight,” she tells the website Philstar, which interviewed her at the couple's Hancock Park home.

Asked what they do, she said, “hug-hug.”

Way to make your man explosive.

And, from the looks of it, Jinkee is hot. So, yeah, you wouldn't want to be the guy facing Manny's gloves tomorrow.

Good luck-luck.
