Manny Pacquiao took part in a training session at a gym in Kuala Lumpur on Tuesday ahead of his WBA world welterweight showdown against champion Lucas Matthysse on Saturday.
The Philippine boxing great, 39, has previously said the outcome of his bout against Argentine Matthysse will likely determine whether he will hang up his gloves after a storied career.
Pacquiao has won world titles across an unprecedented eight different weight classes, but critics - including Matthysse, who is four years his junior - question his ability to box at the top of his game due to his age.
