Cordtz – younger brother of former Warrior Ruben Wiki – is training three hours a day every day for a street workout competition in Thailand in May.
The competition has five classes – freestyle and maximum pull ups – push ups – dips and muscle ups.
Dad-of-four Cordtz 38 can do 120 strict push ups and 35 pull ups.
The former national level age-grade gymnast said he was invited to compete in the contest after video clips of his gravity-defying calisthenics (body-weight) workouts attracted interest around the world.
Cordtz is also in demand internationally to appear at vegan conventions.
He has been on a plant-based diet for two years after trying a 30-day challenge to reduce or even eliminate consumption of meat and dairy products.
‘Within a couple of days I noticed an increase in strength – an increase in recovery – a lot more focus – a lot more energy”.
His body fat went from 15 per cent to 7 per cent in three months.
Cordtz who has Samoan and Maori ancestry is now writing his own 30-day challenges to encourage other Polynesians to try plant-based diets – to tackle diabetes heart disease and cancer.
‘I’ve had three Tongans and three Samoans go vegan because of it so I’m really happy…it’s very encouraging and humbling’.
