Manny Pacquiao has admitted he is addicted to exercise as he fights on into his 40s.
The ring legend defends his welterweight world title against Keith Thurman in Las Vegas on Saturday.
And Pacquiao shows no signs of slowing down as his career enters its twilight.
"I really love exercise, I'm addicted to exercise," he said.
"And even if I don't have a scheduled fight, I always most every day I exercise and I'm playing basketball four to five hours almost every day.
"So when this time comes and when I have a scheduled fight, then I'm so motivated myself to work hard, to train hard, and to focus to the fight.
"Actually after the fight I don't go to the boxing gym. No boxing at all until I have a scheduled fight.
"But I always exercise, like playing basketball, sometimes jogging. But no boxing gym at all.
"In balancing my body conditioning, my mind, and how I work hard, it depends on how I focus and work hard in training. Right now, I still hunger and I'm still enjoying this and happy to do a training preparation for the fight."
Pacquiao's trainer Freddie Roach commended his fighter's work ethic.
"His work ethic is unbelievable, he wants to work every minute of every day," he said.
"He wants to do 40 rounds a day in the ring and so forth; we do have to hold him back a little bit.
"We're on a five-day running schedule right now instead of six and we're giving him a couple extra days off during the week trying to get him not to over train because he does have a tendency of wanting to do that."
