Viewers are being invited into the dressing room of Anthony Joshua in a behind-the-scenes documentary on the boxing star from Watford.

Cameras have been following the IBF heavyweight champion for the last two years for the BBC1 film, which will air later this month.

Watford Observer:

It will show the 27-year-old - who went to Kings Langley Secondary School - in his "dressing room, hotels, at home and in training before and after fights", and preparing for his April 29 encounter with challenger Wladimir Klitschko at Wembley Stadium.

The footage follows Joshua's journey extensively, starting with his clash against fellow Brit Dillian Whyte almost two years ago.

Watford Observer:

In the teasing trailer Joshua can be seen going through the various stages of his hectic life; catching flights, punishing himself with gruelling training regimes and relaxing with his friends and family.

The blockbuster fight is poised to officially break the British record for the number of spectators, with the original capacity set for the bout having been expanded to cater for greater numbers.

The 60-minute film, Anthony Joshua: The Road To Klitschko, will be shown on BBC1 on April 25 at 10.45pm.
