KSI has revealed an astonishing body transformation ahead of his boxing comeback.

The YouTuber’s most recent fight came in 2019, when he defeated long-standing rival Logan Paul in a split-decision win.

KSI, whose real name is Olajide Olatunji, took a hiatus from the sport to focus on his burgeoning music career.

The influencer was performing at Captial’s Summertime Ball when he stunned the Wembley crowd with his toned physique.

The Watford fighter had famously trained with friend Viddal Riley, a promising cruiserweight in his own right.

However, it has been revealed that the pair have split, with KSI moving to a new gym.

Riley has opted to solely concentrate on his own career.

The move had been kept under wraps, but KSI’s strength and conditioning coach Leon Willis has since outlined the fighter’s new coaching set up.

“He’s training with Alexis, part of Shootfighters gym,” Wills confirmed.

The trainer also provided fans with an update on KSI’s current form.

“KSI is looking sharp, watched him spar the other day, very good, very fit. Performed well when I saw him.”

During his time away from the ring, another YouTuber has been making waves in the boxing world; Jake Paul, the younger brother of former foe Logan.

Jake Paul currently boasts a 5-0 record and has visibly improved as a fighter since his boxing debut against none other than KSI’s own brother Deji.

A Jake Paul-KSI encounter has been on the cards since 2019, and many suspect that a face-off is imminent.

The Brit’s ripped physique won’t have done anything to dispel these rumours.

As with most YouTube ‘beefs’, KSI and Logan Paul have since resolved their differences, coming together to launch their own drinks brand Prime.

The pair were forced to cancel a fan meet-and-greet event in London earlier this week after hundreds of fans packed the streets surrounding Asda stores in Leyton and Watford.
