Strength and conditioning coach Angel 'Memo' Heredia expects former four division world champion Juan Manuel Marquez (55-7-1, 40KOs) to be more active in the fight with Mike Alvarado (34-2, 23KOs), set for May 17th at The Forum in Los Angeles, California.

Some felt Marquez, 40-years-old, began to show his age in last October's decision loss to WBO welterweight champion Timothy Bradley. Memo says Marquez's performance was affected because Bradley was always on his toes and never stationary to brawl like Manny Pacquiao. He expects Alvarado to brawl

"Every preparation has to be different, as we have to adapt to a new opponent. We are confident that given style of Alvarado, they will engage with each other - unlike Bradley, [Alvarado] will come out to fight and not to run," Memo said to Erika Montoya.

"People like Floyd Mayweather Sr. believe that Juan Manuel showed signs of age when he fought Bradley, and that he did not look like he used to, but no one factored in the opponent. He was not the same a fighter when facing someone who is just running around the ring. Despite his 40 years, Juan Manuel is in full authority with the effort that he puts into the gym and the work adapts to his needs as time passes. So he is still among the elite."
