Fight week is upon us as the boxing world gears up for another world heavyweight title showdown in Cardiff, Wales on Saturday night in a clash of two undefeated – genuine world heavyweight champions.

Anthony Joshua when you consider has only had twenty professional fights to date in his career has made remarkable progress – both achievements-wise and with regards to his continued growth as a prize fighter.

His fight game has really tightened up under coach Rob McCracken this past year or so with his right hand more compactly thrown from a solid guard and a increased awareness of what is coming back at him and noticeable improvements in his foot work.

At his core though he’s a fighter through and through. He’s been in plenty of exciting fights so far and his vulnerability adds to his appeal in many regards.

One area that has consistently been mentioned as an area that could let him down however is his excessive bulk and emphasis on weight lifting early on in his career.

Traditionally this type of training has slowed down heavyweight prize fighters if you look back at the history of boxing but to Joshua’s credit, he’s always found a second wind so far if he’s fatigued in fights to date.

In this morning’s new video promoting this weekend’s fight it’s a clear area that he particular hears and doesn’t perhaps like this aspect of critcism:

Joshua has made it well-known in the run up to Saturday’s fight that his fatiguing in his last contest against Carlos Takam was brought on by an early broken nose in the fight.

Hindering his ability to breath.

By all accounts Joshua is going to come in much lighter this Saturday than he did against Takam mind you.

Friday’s weigh-ins all shall be revealed.
