Tiffiny Hall is fed up with frauds in the fitness industry.

Instagram has brought us many wonderful things: a platform for emerging artists, accounts dedicated to cute puppies and hilarious memes. But it’s also allowed a bunch of women who’s qualifications end at looking hot, to give out fitness, health and nutrition advice.

And Tiffiny Hall is fed up with it.

“People are spending their good money on bad advice – it makes me angry – and I am fixing that bad advice,” she told A Current Affair during Thursday night’s episode.

Tiffiny Hall speaks to Mia Freedman about sharing a very unconventional post-birth photo. Post continues.

As an experienced personal trainer, with a diploma in sports coaching (and a black belt in Taekwondo to boot) she’s one of the few women with fitness programs qualified to give the advice she does.

But she also knew her limitations and turned to a dietician and psychologist for their expertise when developing her fitness and nutrition program TiffXO.

She told A Current Affair’s Lauren Goldman during their segment exploring the (lack of) qualifications many fitspo flaunters have, that she thinks followers are being duped into thinking a six-pack is a stand-in for actual expertise.

“I’m asked questions in the Facebook community all day – all sorts of questions – and I’m able to respond,” she said, adding that she doesn’t think many of her counterparts are able to do that.

“It takes 10,000 hours to become and expert, not 10,000 selfies,” she said.

Last year Tiff, who is mum to six-month-old Arnold, told Mamamia our focus on short-term, quick fix diets was harming us in the long-term. She added that terms like “clean-eating” – a favourite phrase of many Instagram influencers – could create some really negative habits.

“As a personal trainer, I hear people telling me foods are either good or they’re bad and then that leaks into people feeling ‘well I’m good or bad’. Like ‘I’ve been good today’ or ‘I’ve been bad today’,” she said.

“Diets are often about deprivation and exercise as punishment. Then you hate yourself thin. And what we want to do is to love yourself healthy.

“You don’t want to feel deprived. My biggest tip is to be balanced, to have the food you want, like fish and chips on a Saturday night – and don’t feel guilty about it – but then the next day return to your healthy eating and maybe go for a walk or do some activity.”
