The Baldivis resident who travels to Claremont PCYC twice a week for training was practicing judo and martial arts before wrestling.
‘I always wanted to get in to wrestling but grew up in Geraldton so it wasn’t an option but when I moved here I got in to it straight away,’ Humberston said.
‘I’ve trained really hard on strength and conditioning but I knew it was going to be hard with limited experience.
‘Wrestling is very physical, dynamic and strategic.’
The 25-year-old who trains under greco-roman coach Adrian Tesanovic from the Claremont Tigers Wrestling Club said he carried a 120kg sand bag up and down his backyard about five times a day to improve his strength.
Humberston is preparing to compete in about six tournaments next year and is aiming for the 2018 Commonwealth Games.
He weighs in at 110kg and is six foot 183cm.
He said he would take Christmas Day off but would train during the Christmas break.
