A personal trainer is outraged after discovering that her photos are being used without permission by a gym she has never set foot in to advertise their own programs.

Lyndall Vile discovered that Anytime Fitness in Macquarie Park had taken her 'before and after' photos without permission and appeared to claim she had achieved her figure with the help of one of their trainers.

Ms Vile, who owns her own gym in Sydney, was alerted to the use of her images by one of her own clients. 'He said, "Every time I walk in there I see you on the wall in a bikini,"' she told Daily Mail.

The poster showed two photos of Ms Vile, with text claiming that she lost weight to look good in a bikini. 'Lyndall lost 10kg of body fat in 12 weeks!' it read.

Ms Vile had never been to the gym, and had never given permission for Anytime Fitness to use her photos to advertise their services.

She told Daily Mail that what was most upsetting about the poster was the incorrect information contained on it, as she doesn't support '12 week transformation' programs.

'Don't be a victim': Ms Vile is a powerlifter and says that she trains for performance, not weight loss

The personal trainer posted about the incident to Facebook after she was sent a photo of the poster, saying she was 'outraged' by it.

'The information that they made up to write alongside the image is incorrect as you know I'm not an advocate of "12 week transformations" nor do I care about what you think of me in a bikini,' she wrote in the post.

Ms Vile is also a powerlifter and says she trains to be stronger and perform better, not to look a certain way.She was angry not only about the perception the poster gives about her lifestyle and reasons for weight loss, but the copyright issues with the gym taking her photos.

In addition, the photos of her 'transformation' were more than four years old.

Fast action: Anytime Fitness Macquarie Park told Daily Mail that the 'issue had been resolved' and the poster removed

The director of Anytime Fitness Macquarie Park told Daily Mail that the issue had been resolved.

'Within 30 minutes [of the Facebook post] we had been made aware of it, and within an hour [the poster] had been taken down. Within two hours we had been in contact with the complainant and the issue was resolved.'

However Ms Vile told Daily Mail that she was informed by the director that hers were not the only photos that had been taken.

'They target you': Ms Vile warned that companies use 'bulls**t scams' like this to play on emotions and get women to hire personal trainers

The powerlifter said that she was 'mortified' by it all because of the tone of the advertisement, and warned people to do their research before getting a personal trainer or joining a gym.

'Companies write that s**t because they know that people buy based on emotion,' she wrote on Facebook.

'They know that 90 per cent of the women that walk into their gym don't feel good being in a bikini so they play on your weaknesses. They target you.'
