Steve ‘Commando’ Willis and girlfriend run an outdoor bootcamp in Sydney

Celebrity trainer Steve ‘Commando’ Willis returned to work on Monday after leaked texts laid bare his feud with a former client he claims owes him $1,350 in unpaid fees.

Private messages obtained by Daily Mail Australia last week show Willis, 43, telling a woman named Margaret to pay him the money in one hour or he’ll contact the authorities.

‘I will go to the police if you do not pay,’ the former Biggest Loser star writes in one of the texts, before the woman claims there has been a ‘misunderstanding’.

Despite her protests that she will pay in cash at the start of the next session, Willis says: ‘No Margaret – you have one hour to transfer the money.’

The dispute between the pair escalated on Sunday when Margaret, whom Willis accuses of stalking him, reported him to police over a supposed breach of social distancing rules at one of his outdoor bootcamps in Sydney’s north-west.

The trainer’s spokesperson said officers had been called to Willis’ home ‘regarding a reported breach of social distancing’ but he denied any wrongdoing.

‘He confirmed with local police that he was operating as per current regulations,’ they added.

The representative claimed that police had been called out of spite ‘because [Willis] had made a formal complaint to them about a woman identified as “Margaret”‘.

‘Steve has been in contact with the police again today regarding ongoing stalking from Margaret. We are in the process of seeking appropriate legal measures against her,’ they said.

A NSW Police representative told Daily Mail Australia: ‘About 1pm today [Sunday], an officer from The Hills Police Area Command attended a home in Beaumont Hills, following reports a woman was seen in the area.

‘Police spoke to the occupant to discuss any possible further action. However no further information is available at this time.’

Margaret told The Daily Telegraph she had reported Willis for ‘breaching social distancing rules at his classes’ but denied she had been ‘stalking’ him.

Willis shared a number of photos and videos to Instagram on Sunday that appeared to show the training session in question.

Meanwhile, it was business as usual for Willis on Monday as he and his girlfriend, Harika Vancuylenberg, ran an outdoor fitness class in Sydney.

During the session, the fitness-loving couple directed clients through a series of exercises, some of which involved lifting heavy weights.   

The powerhouse pair worked seamlessly as a team throughout the session, and were regularly spotted convening with each other from the sidelines. 

They even shared a drink bottle and wore matching outfits emblazoned with the logo of Willis’ brand, CommandoFit.

Last Sunday, Willis, Vancuylenberg and Margaret had been filmed getting into a heated argument at a park in Sydney’s north-west over alleged outstanding fees. 

Margaret claimed she did not owe Willis the $1,350 he was asking for.

Video footage later went viral showing Willis and Vancuylenberg angrily confronting his former client.

Margaret was filmed approaching the pair as they packed equipment into their car following a group fitness session.  

‘You are not engaging with him. You pay him what you owe him,’ Vancuylenberg screamed in the footage.

‘No money, no talking! He has told you $1,300. That is what you owe him.’

Margaret responded: ‘If you don’t agree we can go to court, because I have the record that I paid you.’ 

Margaret – who wished for her last name not to be published – insisted she had already paid Willis, who has been training her since April last year, and provided Daily Mail with their Instagram messages.

‘Until this is done there will be no further training,’ Willis wrote in one message. 

Dispute: The woman who made the complaint is a former client of Willis' who has been embroiled in an ongoing dispute with him over 'unpaid fees' the trainer claims she owes

The back and forth between the pair continued, before Margaret asked Willis to meet up with her face to face to pay him in cash.

‘No Margaret – you have one hour to transfer the money,’ he said.

Margaret responded: ‘I didn’t say or mean I’m not paying you – you just get angry and [run] away.’

Margaret, who saw Willis two to four times a week since last April, claims she paid him in cash at the start of every session. 

In messages to Margaret on May 20, Steve claimed she owed him $200 for each personal training session on April 17, and April 21, May 1, May 4 and May 5.

Margaret continued to ask to meet up with Steve in person to pay him in cash, but Steve insisted she simply bank transfer the unpaid money and call it a day.

Margaret said the public spat had broken out shortly after she drove to the public reserve to confront Steve about the payments.

‘When I parked my car in the car park and still in the car, Harika sent her two kids, a boy and a girl, to come around my car to check me,’ she claimed.

‘There was nobody else around my parking spot so it was very obvious. I didn’t want to get involved with any kids. So I drove off to get a coffee.

‘When I came back I parked in a different spot, I saw in my mirror that Harika came to the rear of my car and started to take photos of me when I was sitting inside.’

Margaret said this is when the confrontation was sparked, before she pulled her phone out to film the incident.

Willis is yet to confirm his relationship with Vancuylenberg, who works as a trainer at popular fitness franchise F45.

They were recently pictured holding hands in Sydney, following his break-up with fellow celebrity trainer Michelle Bridges in December after eight years of dating.

It has been reported the pair met in November on a fitness retreat in Tahiti, but did not start dating until February, after he’d split from Bridges.
