He's a full-time public servant who trains in his own backyard gym at 9pm after his two daughters go to sleep.
And proving he never rests, O'Connor's Jim Hosie has won a third national title in a third different sport nine years after claiming his first.
The 35-year-old was last week crowned Australia's Greco-Roman wrestling champion in the 120-kilogram class, having won national titles in natural bodybuilding in 2003 and powerlifting in 2010.
But Hosie has turned down the opportunity to represent Australia at the wrestling world championships in Canada in September, because he doesn't want to leave his young family behind. Hosie's biggest supporters are his wife Danielle and daughters Ellie, aged four, and Katja, one.
''It's hard having a young family trying to keep a routine together, it's challenging,'' Hosie said. ''I train at night between nine and 10 when the kids are asleep. I want to make it as less an impact as possible.
''It's something I'm teaching my kids. You learn from competing, you learn from defeat - you can learn how to win.''
Hosie's passion for wrestling allowed him to fall into natural bodybuilding in 2003 where he earned his first national title. After losing interest in body building he entered powerlifting in 2010. He achieved his second title and overcame a lower back injury to break records.
''Powerlifting was special to me after overcoming bulging discs and then beating three 16-year-old records. It tested me the most,'' he said.
Hosie hit his hat-trick of Australian titles with Greco-Roman wrestling after tearing his hamstring in a social touch football game just weeks before the titles. He said it wasn't ideal before the fight in Perth.
''The hamstring injury put me out of training for four weeks,'' he said.
Hosie's determination pulled him through and he came home with the gold medal.
Hosie gains motivation from the support of family and the efforts of his coach Witold Reijlich.
''We are very lucky to have a coach of Wiltold's calibre in the ACT,'' he said.
Hosie's next challenge will come at the qualifying event for the Oceania championships next year and he is sure to have his family close by. ''I'm lucky to have such strong support,'' he said.
