Willis rose to fame in 2007's The Biggest Loser when the former soldier found love with co-star Michelle Bridges.

Before their split in 2020, the former power couple built a fitness empire together and Willis published books like Commando Steve: No Excuses and Get Commando Fit – and he even starred on a season of Australian Survivor.

But following his split from Bridges and exit from The Biggest Loser in 2015, Willis, 47, largely disappeared from the public eye, leaving fans wondering what he's up to these days.

Although Commando is no longer on prime time television, it is still a major player in the fitness industry.

He currently runs his own gym in Sydney called Get Commando Fit, and also works as a personal trainer and offers online classes.

Willis also runs a children's fitness program called Commando Kids and hosts his own grueling fitness camps.

His private life also blossomed and he found love with the former F45 trainer Vancuylenberg.

The couple apparently met in November 2019 when Harika attended one of Steve's fitness retreats in Tahiti and confirmed their relationship in July 2020.

Harika now helps run Steve's fitness empire and represents the gym in fitness competitions across Australia.

Although things are going well for the couple, both have ruled out having children together.

Willis is already the father of four children, including son Axel, who he has with his ex Michelle, while Harika has two children of his own.

Michelle and Commando first met while filming The Biggest Loser together and welcomed Axel in 2015 before both left the series.
