Anthony Joshua is dropping knowledge in his latest collaboration with Under Armour.

Ahead of his titanic unification fight against Joseph Parker in Cardiff, AJ has linked up with Under Armour to front their latest campaign, which focuses on the mental aspect of preparation.

Directed by the multiple award-winning Walter Campbell, the film sees Anthony Joshua reciting an inspirational piece of prose that reflects his attitude to the internal battle all athletes must win to reach their full potential. The film shows this mental fight with AJ engaging in combat against his own shadow. The ‘fight’ is brought to life via the interplay of light and shadow throughout the short film, while the shadow is depicted as a manifestation of the mental and physical progression Anthony Joshua must undertake to reach his pinnacle.

Speaking on the film, Anthony Joshua said:

"The mental is as important as the physical. That voice in your head telling you to keep going, to delve deep in to your character. You have to make sure that if your body wants to stop, your mind won’t let you.

I put the hours in, work harder and smarter than my opponents, but that counts for nothing, if my head is not in peak condition. Your body can be hurt and tested, but your will must be invincible."

Anthony Joshua – who works with Under Armour as his official footwear, training and apparel partner – steps inside the ring to face Joseph Parker on March 31st.
