IBF welterweight champion Kell Brook (36-0, 25KOs) turned heads recently, when he weighed at 176-pounds for the WBC's 30-day weight check.

The weight procedure was part of the mandatory requirements for the upcoming showdown with WBC/IBO/IBF/WBA middleweight champion Gennady 'GGG' Golovkin (35-0, 32KOs). The fight takes place on September 10th from the O2 Arena in London.

Golovkin only weighed 165-pounds, 11-pounds, less, at the WBC's weight check. Brook, viewed as the smaller man, is moving up by thirteen pounds for the fight.

Golovkin, even 30 days out, is close to the middleweight limit of 160. Brook is nearly 30 pounds beyond his usual fighting weight of 147 - which casts a lot of doubt that he'll be capable of dropping back to the welterweight limit in the future.

Brook says the extra poundage is intentional and based on a strategy formulated by the entire team, which includes head trainer Dominic Ingle.

"I'm normally heavy. Not as heavy as I am now but with the science behind it, I've been working my legs with the weights but keeping the speed and movement. I've been using all the ring and probably a bit too much, getting used to moving a lot because anything that can happen on the night," Brook told Sky Sports.

"I'm heavy but I'm using this heaviness as I would as a welterweight - keeping the speed but I'm more vicious, more natural and stronger at this weight. I'm working on a few things but this is the fight of my life so I'm keeping it to myself. Nobody in Britain has done what I'm going to do on September 10 - shock the world by jumping up two weight divisions to beat the man everyone's afraid of.

"Anything we're working on, we're keeping close to our chest. This is the fight and you can get hurt in there so I need to be 100 percent in it."
