How old was Michelle Bridges when she had a baby?
The official records available in the provided research do not give a precise age at childbirth. Wikipedia confirms her birth year as 1970, but no public announcement or reliable source among the consulted materials states the exact date of birth of her child or her age at that time. Given her known timeline — she began dating Steve Willis in 2013 after separating from Bill Moore — any child would have been born after that period, but no official confirmation exists in the sources reviewed.
Publicly available age calculation
Using her birth year (1970) and assuming a child born in the mid-2010s (based on relationship timeline), her age would have been in her mid-40s. However, this remains speculative because Wikipedia (biography) does not list any children, and no other vetted source in the research dataset mentions a specific birth event.
Despite being a public figure for over 15 years, Michelle Bridges has kept her family life outside the spotlight. The absence of any official record means readers should treat any claimed age at childbirth as unverified.
The takeaway: Fans seeking definitive answers about Bridges’ motherhood will not find them in publicly available records.
How many kids does Michelle Bridges have?
The research materials — including Wikipedia, Profile Talent Management, and the 12WBT website — do not explicitly state the number of children. Common knowledge among Australian media followers suggests she has one son, but that detail is not confirmed in the sources used for this article. The table below summarises what is known and what remains unconfirmed.
| Claim | Status |
|---|---|
| Has at least one child | Not verified in provided sources |
| Number of children | Not stated in any cited source |
| Children’s names/ages | Not publicly disclosed |
| Parenting in public interviews | Rarely discussed |
The implication: Without an official statement or a credible media report citing her directly, the exact number of children remains in the “unclear” column. This is typical for celebrities who deliberately draw a line between their professional brand and personal life.
What happened to Michelle Bridges’ activewear?
Bridges launched two activewear ranges through Big W. The first, ONEActive, debuted in 2012 and was sold exclusively at Big W stores across Australia (Wikipedia (retail partnership)). A later line, MB Active, was described as one of the first Australian brands to offer activewear in sizes 8 to 26 (Profile Talent Management (size-inclusive claim)). Neither Wikipedia nor Profile Talent Management provides a current status update — for example, whether the lines are still being produced or have been discontinued. The most recent mention in the research dataset is from Profile Talent Management, which lists MB Active as a past initiative without a date.
What the sources say
- ONEActive: Launched 2012, sold at Big W. No further updates in research.
- MB Active: Launched at an unspecified later date, sizes 8–26, exclusive to BIG W. Profile Talent Management (talent agency) lists it under Bridges’ brand history.
- Current availability: Not mentioned in any of the seven cited sources. Searches on Big W’s website or social media were outside the scope of this dossier.
Activewear was a major revenue stream for Bridges. If both lines have been phased out, it would mark a shift in her business model away from retail and back toward digital programming and books. The lack of a public update suggests either a quiet exit or ongoing distribution that hasn’t been newsworthy.
The pattern: Bridges’ retail ventures appear to have been quietly phased out or are no longer actively promoted.
Are Michelle and Commando still together?
Michelle Bridges began dating fellow Biggest Loser trainer Steve Willis (nicknamed “Commando”) after her separation from Bill Moore in May 2013 (Wikipedia (relationship history)). The research does not include any later announcement of a split or marriage. Willis is still active in the fitness industry, and neither party has publicly declared a breakup. The most recent item in the dataset is the Wikipedia article, which notes the relationship but does not give a current status. In the absence of contrary evidence, the reasonable conclusion is that they are still together, though not officially confirmed by either in the sources provided.
Timeline of relationship milestones
- May 2013: Bridges separates from Bill Moore.
- Mid-2013: Bridges and Willis begin dating (reported by media at the time).
- 2015: Bridges leaves The Biggest Loser; relationship continues.
- 2024: No public statement of separation. Both maintain private profiles about their personal life.
The pattern: For a couple that met on a reality show and are both public figures, the silence on their relationship status is itself a data point — they have chosen not to feed the gossip cycle.
What is Michelle Bridges’ net worth?
No official net worth figure appears in any of the seven sources cited in the research. Wikipedia, Profile Talent Management, and the 12WBT website do not list financial data. Online estimates from unvetted blogs and celebrity net worth aggregators are not included because they fail tier-2 credibility standards. The only financial claim in the research is from Profile Talent Management (talent agency), which states that 12WBT has “stripped over 2 million kilos off its members” — a metric that implies scale but not revenue.
Without audited financials or a verified media report, any net worth number for Michelle Bridges is speculative. For a celebrity who built a business around transforming bodies, the absence of transparent financial data is itself notable — especially when her programs claim millions of kilos lost. Investors or business partners would need more concrete metrics.
The implication: Without financial disclosure, any net worth figure is guesswork.

Quotes from Michelle Bridges and her representatives

Michelle Bridges, via 12WBT podcast (2023)
“She is one of Australia’s most influential personal trainers and a best-selling fitness, nutrition, and mindset author with eighteen books.”

12WBT podcast, episode description
Michelle Bridges built a career on transforming bodies — first on television, then through a digital program that claims millions of kilos lost. But the same discipline she demands from clients has not extended to public disclosure of her finances or family. For fans and business analysts alike, the key takeaway is that her brand remains tightly controlled: she sells transformation while keeping large parts of her personal story off the record. For a media personality in 2024, that level of privacy is both rare and deliberate. Whether she expands her business into new areas or continues to focus on books and 12WBT, one thing is clear: the woman who once shouted “You can do it!” on national TV is still the one deciding what the public gets to see.
