Max Key has revealed a secret ability and taken on the world at a recent global Jiu Jitsu competition.
Key, the son of former prime minister Sir John Key, posted the update to his Instagram, telling followers he had been keeping his jiu jitsu journey quiet.
He said he had first walked through the doors of the gym six months ago with "no martial arts experience, low self-confidence and a desire to put myself out of my comfort zone."
Key said he has been training with Douglas Santos at Santos' DS Team gym in Auckland and credited his sensei with his success at the Jiu Jitsu Con event in Las Vegas,
"My sensei @douglasnz quickly took me under his wing and convinced me to start competing and to push my mental and physical limits. For five months we trained morning and night twice a day and I was pushed harder than I could've ever imagined," Key said.
