MANNY PACQUIAO’S camp has downplayed the new more muscular physique of Mexican Juan Ma-nuel Marquez, which the latter developed through weight lifting and old school training such as chopping wood with an axe and hitting old tires with a sledgehammer.

“Freddie doesn’t care about Marquez’s muscular form. He is not worried,” Pacquiao’s long time lawyer Franklyn Gacal told The Manila Times in a telephone interview. “Pacquiao’s training in US really looks good and everything is alright. Manny, for his part, will do his best to knockout Marquez.”

Pacquiao’s head trainer, the legendary Freddie Roach said that a more muscular body does not equate with an unbreakable chin.

“I don’t think having big muscles will give him some advantage or provide him a better chin. More muscles will add more bulk on him and he’ll become slow. We’ll take advantage of that,” Roach told reporters during a teleconference organized by philboxing.com recently.

Pacquiao’s strength and conditi-oning coach Alex Ariza said that he’s utilizing an approach that is very different than that of the Marquez’s.

“No I don’t do that with Manny, theory for JMM [Juan Manuel Marquez] is that he is going to use short explosive bursts with power versus volume punching,” Ariza posted on his twitter account @ArizaFitness.

A week before the fight happens on December 8 at the MGM Grand in Las Vegas, Nevada, Pacquiao will halt all training to rest his body.
