Anthony Joshua has been showcasing his defensive skills as the build up to his duel with Wladimir Klitschko gathers pace.
The 27-year-old posted a video on his Instagram and Twitter page where he was seen dodging tennis balls at high speed during an intense training session as he continues his preparations for the April 29 showdown.
The IBF heavyweight champion has knocked out all 18 opponents he has faced during his professional career, but the 27-year-old was keen to demonstrate his defensive might.
Joshua knows he has to be at the peak of his powers to overcome Ukrainian Klitschko. The 41-year-old is vastly more experienced and has racked up 53 KOs throughout his career.
Joshua and Klitschko will square off in front of 90,000 people at Wembley Stadium for the WBA, IBF and vacant IBO belts in four weeks' time.
Joshua's last beaten opponent, Eric Molina, thinks the Briton stands head and shoulders apart from his other rivals.
"He's a great champion and I personally do not see too many heavyweights beating him, he's very strong," Molina told Sky Sports.
"One thing that Joshua has shown is, he's getting bigger, better, faster, stronger, every fight.
"I don't want to disrespect Klitschko, but the torch is going to be passed that night. If it hasn't been already, I think it's going to officially get passed."
