Graham Norton tried out boxer Anthony Joshua’s training routine

And Tom Hanks stole a line from our Late Late Show

In a preview for tonight’s Graham Norton show, the host himself tried to copy one of Anthony Joshua’s training routines.

And it’s a lot harder than it looks.

Norton shows a video of the heavyweight champ training in an exercise that saw AJ punching a tennis ball attached to a hat.

It looks easy, but as Norton proves it is actually pretty tough.

Make sure you watch to the end, where Tom Hanks shouts a famous Late Late Show phrase.
