Anthony Joshua gave everyone a glimpse of what his pre-Andy Ruiz Jr training camp is like in a promotional challenge on the William Hill YouTube channel with boxing newcomer KSI.

At the beginning of the video, popular presenter David Alorka introduces Joshua as the ‘soon to be two-time heavyweight champion of the world’, putting a rather big smile on the former champion’s face.

In part one of the series, they measure Joshua’s speed with a speed bag challenge, and it is fair to say that Joshua – as many might have expected – looked in perfect form ahead of his career-defining rematch with Ruiz Jr on December 7 later this year.

The challenge tests just how many accurate small punches Joshua can throw in 20 seconds; the British champion recorded an impressive 69 punches, but that might mean very little to most supporters.

So, in order to compare, YouTube boxing champion KSI was introduced to rival Joshua’s score and to see just how good it really was.

KSI started his career on YouTube itself, predominantly making FIFA videos before making a switch to music in recent years.

Then, after a social media spat ensued, the influencer took to the sport at white collar level. In just two fights with fellow YouTubers Joe Weller and Logan Paul, the former gamer had raked in over 10 million views, selling tickets on pay-per-view.

This incredible audience piqued the interest of Matchroom Boxing promoter Eddie Hearn, who decided to take his upcoming rematch with Paul after the first bout ended in a controversial draw.

The bout will be a professional fight with no headguards and will be shown on DAZN and Sky Sports.

KSI – who continually makes it quite apparent that he isn’t nervous about the result of his upcoming fight on November 9 – instantly reverted back to his witty ways after telling Joshua he has a different technique to him.

This ‘technique’ was to hit the bag as lightly as possible really quickly so that his energy is conserved, and his accuracy remains on point.

Even after essentially cheating, KSI only managed to hit the bag 52 times in 20 seconds, meaning he was still 17 off Joshua who was hitting much harder.

Alorka also had a go and managed just 35, emphasising that Joshua is on a completely different level.
