Heavyweight boxing superstar Andy Ruiz appears to resemble Mike Tyson during one of his recent open workouts and has received some advice from the legend ahead of his rematch with Anthony Joshua.

The much-awaited rematch between Joshua and Ruiz is finally happening in a few days. As the two heavy-hitting champs prepare for their second showdown, then-underdog Ruiz demonstrated some routines which appeared to mimic the moves of Tyson.

In a recent video uploaded by veteran boxing reporter Elie Seckbach of EsNews, Ruiz can be seen working on some lethal moves inside the ring. Together with his trainer, Ruiz showed off his Tyson-like agility and power.

Despite not having an incredibly athletic physique, Ruiz surprised everybody in attendance by displaying almost the same head movement and combinations as Tyson. Although the legendary boxer is still a lot quicker than Ruiz, especially during his prime, the movements appear to be almost identical.

Last September, Fighthype.com released a “throwback Tyson open workout” with Hall of Fame trainer Freddie Roach. The video was taken a few days before Tyson faced Danny Williams in 2004. During that year, Tyson was already a bit past his prime.

However, as Roach and Tyson proceeded, it was evident that “Iron Mike” still carried “explosive” power in his hands. The Tyson in the said video is arguably the most identical to the recent Ruiz. In terms of power, it was kind of hard to determine who hits harder but as for the speed, it appears that the 2004 Tyson is a little bit faster.

Part of his preparation for the rematch with Joshua, Ruiz has decided to lose some weight. For the Mexican champ, he believes that losing a couple of pounds will help him in some aspects. However, Tyson himself is not in favor of Ruiz cutting some weight in the hope to perform better on the rematch.

Speaking to Parimatch, the 53-year-old legend questioned Ruiz’s decision and even revealed what the reigning champ really has to do in facing Joshua once again, Sport Bible reported.

“I just don't think that makes any sense . But everybody has their own thing, their vanity gets the best of them, they say 'Hey, I wanna look good doing this stuff', I don't know,” Tyson said about Ruiz’s weight loss.

"But I'm a believer that if it's not broken, don't fix it. The only thing Ruiz has to do is do what he did last fight. That's all he has to live off of, from his memories, so to speak, from the last fight," Tyson pointed out.
