Pacquiao vs. Spence Update: Filipino Boxer Works On 2 'Explosive' Moves For Fight

Manny Pacquiao may have hinted at what Errol Spence Jr. would be dealing with in their highly-anticipated title fight.

At 42 years old, Pacquiao is once again stepping inside the ring to take on his fellow southpaw and welterweight champ Spence on Aug. 21.

Shortly after announcing his return, “Pac-Man” reunited with his team and began training. In a recent training video uploaded by Fight Hub TV, Pacquiao could be seen perfecting some "explosive" uppercut and body shot combinations with his trusted trainer and friend, Buboy Fernandez.

In the middle of the intense workout session, Fernandez could also be seen seemingly giving Pacquiao some instructions on how to effectively pull off the said power punches.

Pacquiao is coming off back-to-back 12-round fights in the welterweight division. However, he has gone 25 months without boxing, and some believe that the inactivity could take a toll on the world’s only eight-division titlist.

According to Pacquiao’s assessment, “stamina and good conditioning” are vital for a fighter like Spence, and the undefeated American champ poses a more serious threat to him than his last three opponents.

"I need to have stamina and good conditioning [for the Spence fight]," Pacquiao exclusively told Boxing Scene. "In this fight, you have to expect more action in the ring compared to my last three fights. I have to make sure that my stamina is enough so I don't fall short in all 12 rounds."

Spence is coming in with a height and youth advantage over Pacquiao. Due to the Filipino boxer’s age, naysayers and pundits have suggested that he should consider calling it a career.

However, Pacquiao appears to still be undecided about the matter as he is still leaving the door open for “more fights” after Spence.

"It's hard to say right now,” he said about the idea of retiring after the Spence fight.

“It could be, but there could also be more fights after this," he added. "I'm taking it one at a time. We can't tell the future."

At this point, the only thing certain is that Pacquiao isn’t in it for the money.

"If this is just for money, I would have chosen someone weak and not a boxer,” the reigning WBA super welterweight champion recently said on Noli Eala's "Power and Play" show. “If this is just for the money, why would I take on an undefeated boxer? This is the real fight; not a fight where your opponent is not a boxer."

"I'm not like any other boxers out there, who is just fighting for the sake of money, fighting someone who is not even a boxer. What I want is a real fight; to challenge the best. It's always been like that," he continued.
