Anthony Joshua uses mattress as a punch bag to train for his next big fight

Anthony Joshua is currently undergoing preparations for his potential August fight against Dillian Whyte, and has posted a video of himself improvising when it comes to training.

The former heavyweight champion could be seen in the clip punching a mattress, as if it were a punching bag.

Naturally, Tyson Fury was quick to weigh-in on the situation, commenting 'Proper sausage' alongside laughing emojis under the post.

The last time AJ took on Whyte in 2015, he walked away victorious with a knockout.
