ANTHONY JOSHUA is famous for many things. Olympic gold at London 2012. Becoming a heavyweight world champion. Beating Wladimir Klitschko in front of 90,000 and unifying heavyweight titles. He’s also known for training with unrelenting intensity.

Joshua advises, “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.” 

He continued, “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.”

Under Armour, one of his key sponsors, have produced a short film to dramatise the struggle. Watch below:
