Andy Ruiz American born Mexican boxer is putting himself in perfect shape ahead of his rematch with Anthony Joshua in Saudi Arabia later this year.
The 30-year-old emerged WBA, IBF, WBO and IBO heavyweight champion in June after flooring the British pugilist at the Madison Square Garden.
However, with less than two months to the much-awaited fight staging in Diriyah on December 7, Ruiz seems to be fully ready for the bout.
Speaking to ESPN Deportes, Ruiz said: "I have a lot of respect for Anthony, outside the ring he is a very good man. "But inside [the ring] there are no friends, there is no respect or anything.
"It will not be an easy fight. I think it will be a hard fight, but nothing is easy in life, so we are training very hard. We will be prepared for whatever he bring.
"I will arrive in better condition.... lighter, faster and more powerful. They will believe that in December they will win.

"People will always talk like this, but I have faith that we're going to win and shut up more mouths."
The WBO, WBA and IBF heavyweight world champ was said to have added weight last month, but recent photos show the boxer shed weight.
SunSport further report that he has changed his diets and choice of Snickers, for healthier options like fruit and nuts.
Joshua on his part has also been working so hard to shape up for the fight in the Middle East - with his fans happy with his new look ahead of the match.
One said: "Joshua looks a lot better now he's shedded the weight. Like he just wanted to pose for Instagram before."
A fellow user wrote: "Yes AJ. The 2014/15 lean, mean, hook-wielding, uppercut-throwing machine is back by the looks of things."

Another commented: "Anthony Joshua cutting plenty of weight for his rematch with Andy Ruiz Jr is absolutely what's needed."
A fellow user posted: "AJ appears to have lost some muscle mass which is great, he was better when not as big."
Another comment read: "AJ was way too heavy for the first fight. This time he's already shaved all that muscle off. Light work this time, he's going to ruin Ruiz."
Legit.ng earlier reported that former world heavyweight champion Anthony Joshua has vowed to exploit Andy Ruiz Jr's ‘weaknesses’ during their December 7 rematch.
The 29-year-old pugilist suffered his first professional defeat in June after he was sent to the canvass four times by Ruiz as he lost the WBA (Super), IBF, WBO and IBO heavyweight titles to the Mexican-American.
However, with the rematch closing in, 'AJ' has now admitted he knows how best to the deal with the 29-year-old Mexican-American.
