Anthony Joshua works up a sweat using chains and ropes in build up to Joseph Parker showdown

ANTHONY JOSHUA is back in training for his unification blockbuster fight against Joseph Parker - and as these photos show, it's a gruelling training camp at that.
Joshua will meet Parker at Cardiff's Principality Stadium on March 31 in a fight that sees four heavyweight title belts on the line.
It is the second successive fight Joshua will take part in at the Principality Stadium, having defended his IBF, WBA and IBO titles against Carlos Takam there in October.
Joshua is aiming to see off the challenge of 26-year-old Parker before targeting a clash with American Deontay Wilder later in the year.
The aim is to win both fights to become the undisputed world heavyweight champion by the end of 2018 as Joshua looks to seal his legacy in the history of the sport.
Joshua has always been known to have a high-intensity camp before fights, and this time is no different.
The Watford boxer has incorporated ropes and even chains into his training as he targets adding another heavyweight word title to his waist.
New Zealand's Parker is undefeated in 24 professional fights with 18 of those wins coming by knockout meaning that after the fight.
Tickets for the blockbuster Heavyweight World title unification clash between Anthony Joshua MBE and Joseph Parker went on pre-sale to Matchroom Fight Pass members at midday on Monday.
They are now on general sale on ahead of the March 31 event live on Sky Sports Box Office.
