On how earth did Ruiz manage to gain another stone in weight for the fight? Wouldn't the 6 weeks of training whipped him into shape?

At the post match conf, Ruiz said that he ignored his trainer's and father's advice to focus on the training and cut out of the partying. He also confessed to not taking Joshua seriously and thinking he'd win.

If Ruiz had managed to get in shape; gain some muscle and become lighter, I think he would have stood a better chance. TWinning the 2nd fight would have set his grandkids  up for life.
