Fans can't believe how much liquid comes pouring out of Canelo's sweat pants

Saul 'Canelo' Alvarez has begun his weight cut for the Gennady Golovkin trilogy bout and, well, let's just say he's a pretty sweaty boy.

Video has emerged online of the boxing world champion emptying his trousers after a tough training session and the sweat literally comes pouring out.

Footage of the Niagra Falls has started doing the rounds on social media and fans genuinely can't believe how much liquid there is.

Canelo and GGG are just days away from revisiting their legendary rivalry with a third, and perhaps final, fight.

After a draw in the first match-up, it was Mexican fan favourite Canelo who won the second of their two clashes, although many boxing purists believe Golovkin was robbed by the judges.

So after a rather unsuccessful trip up to the light-heavyweight division, Canelo is moving back down defend his undisputed super-middleweight title once again.

And he's facing off against an even-hungrier GGG eager to exact revenge.

Fluctuating in weight is never a good thing for the body to endure, but by the looks of things, Canelo is having no problem with shedding the pounds ahead of the trilogy.

In a video posted on social media, liquid can be seen gushing out of Canelo' tracksuit pants after a rigorous session in the gym or even sauna.

When fans saw the footage shared by boxing reporter Michael Benson, they couldn't quite believe their eyes.

One commented: "I’ve never seen someone sweat that much."

While another added: "At first glance I thought he had just come in from running in the rain."

Granted, Canelo is wearing a sweat suit, but still – it's A LOT of liquid.

As for Golovkin, he shouldn't be 'sweating' too much on the cut.

The Kazakhstani icon usually competes at middleweight but will jump up to super-middleweight to challenge Canelo, meaning he doesn't have to lose as much weight.

"Indeed, it's a new weight division for me, and there are certain nuances, and we are making appropriate adjustments," GGG told Yahoo Sports.

"My focus is on heavy training and my experience. I think the difference would be in making this weight, so I feel very comfortable making 160.

"From from time to time, I will have to probably wear this weight burning suit a couple of times, while, for 168, there is a chance that I will not need it."
