Newly single Biggest Loser trainer Michelle Bridges has a healthy appetite for life Michelle Bridges and Bill Moore are still the best of mates. Picture: Matrix Source: Supplied SHE'S the empress of a burgeoning fitness fortune and, despite the recent breakdown of her nine-year marriage to business partner Bill Moore, Michelle Bridges still has plenty to smile about. With seven books, a gymwear and equipment range and a body transformation program in her portfolio, industry estimates put the super-ambitious Biggest Loser trainer's worth at a self-made $12 million. The 42-year-old social scene regular maintains she and Moore remain the "best of friends" and will continue to work together, despite admitting last week that professional endeavours had driven a wedge in their relationship. On Sunday the couple - who met while Bridges was working at Moore's gym 12 years ago - were captured lunching at Woolloomooloo, arms linked as they left the restaurant. The bulk of Bridges' earning are said to have come from her "12 Week Body Transformation Challenge," an all-online exercise and nutrition course the pair launched in 2010, which is now used by thousands of people all over the country. Before Biggest Loser, (Michelle) used to spend night after night at the computer writing and submitting articles to every fitness magazine. She never got paid. She just wanted to get her message out," Moore told the Australian Women's Weekly in 2011.
