HEAVYWEIGHT brute Anthony Joshua showed off the explosive power that has seen him knockout 21 of his 24 opponents.
The WBO, WBF and IBO champ looks in incredible shape as he continues to bulk ahead of his showdown with Bulgarian powerhouse Kubrat Pulev in December.
AJ dropped almost a stone following his disastrous loss to Andy Ruiz Jr in June 2019, after teetering the scales at 17st 9lbs, to get his revenge on the Mexican.
But he appears to have piled on the muscle once again which was evident on a training video uploaded to Instagram, captioned: “Beauty in violence.”
During a workout session, he works on his power by throwing a brutal right uppercut, left hook combo on four occasions.
He knocks his trainer off his feet and those in the background watching can be heard gasp in amazement at his strength.
One fan responded online: “This is why Anthony Joshua is the greatest boxer of all time.”
Another added: “If either one of those lands it’s curtains for Tyson Fury.”
Joshua’s promoter Eddie Hearn insisted his fight with Pulev will still go ahead as planned despite being behind-closed-doors.
The government have performed a U-turn on plans to allow a minority of fans back into sporting arenas from October.
He told the Daily Mail: “Obviously today’s announcement is a massive challenge for everyone in sport.
“Our intention now is carry on with all our scheduled events.
“Clearly the finances are affected by not having crowds, even smaller crowds, but we’re working to keep our schedule. That includes Joshua.
“You have two options – cancel or go ahead, quite possibly without a crowd.
“You’d still hope that by December you might have some back but you can’t plan on that now.
“We’ll go ahead in December for Joshua because it’s been a year since he fought Andy Ruiz and he needs to fight.”
