World heavyweight champion Anthony Joshua is poised to reveal the date of his blockbuster rematch with Wladimir Klitschko any day now but in the meantime has swapped the boxing gloves for a tennis racket.

The WBA, IBF and IBO boxing champion is a big tennis fan and to hone his lightening quick reflexes the hulking star has come up with an ingenious workout to merge his two sporting loves.

With the help of one member of his trusted training camp, his right hand man JC Elite, Joshua has been testing his speed.

His friend and coach JC – who is also a top tennis coach – drilled a series of backhands and forehands at the champ as he stood pinned against a wall on a tennis court in Las Vegas last week.

Posting a clip of the training session to his Instagram account, JC captioned it: ‘Slipping shots + reactions with @anthony_joshua good to mix up the training #tennis #ajboxing #jcelite.’

Joshua, who is expected to face Klitschko again in November in Las Vegas and is due to announce the news this week, is a keen tennis player himself and counts world No 1 Andy Murray as a close friend.
