Even if his next ring appearance is an exhibition, Manny Pacquiao insists on not shortchanging those who will pay to see him face mixed martial arts expert DK Yoo live next week in Seoul, South Korea.

"I have always loved training and pushing myself," Pacquiao said yesterday from General Santos City.

Pacquiao, who turns 44 on 17 December, has been diligently reporting for afternoon workout for the past two months.

The future Hall of Fame inductee swears training hard is in his DNA.

"It's in my system," he added.

In winning eight world titles in as many weight classes, hard work was a pivotal part of his success.

During his training camps at the Wild Card, Freddie Roach and the rest of the training team always had to beg Pacquiao to stop.

Once again, the scene is repeated as Pacquiao continues to cross the boundaries.

Already retired from boxing for over a year now, Pacquiao does everything for the Yoo buildup as though he is revving up for a world title fight in Las Vegas.

Again, Pacquiao is not holding any punches.

And that's bad news for Yoo.
