GOLD Coast fitness model Andy Page posted a video on Saturday morning about her “lean breakfast” and upcoming workout

The next morning she was dead.

The 32-year-old went to bed on Saturday night with pain in her side and never woke.

Devastated family, friends and colleagues have posted their grief on social media and are at a loss to explain what caused her death.

Gold Coast boxing promoter Jamie Myer trained Andy for her first amateur fight and said she was the type of person who “lit up the room”.

“Any was a happy, bubbly girl, who always lit up a room and gave 100 per cent to everything she did,” Mr Myer said.

“We got her in the ring for her first fight and she loved it. It was one for her to tick off the bucket list.

“She had no comps coming up and was a hard-worker who trained the right way.

“She was recovering from an injury and had just moved back to the Gold Coast from Sydney.”

Mr Myer flatly dismissed speculation the sports model was using drugs.

“She just wasn’t that kind of girl,” he said.

Andy lived on the Gold Coast, worked as exercise physiologist, swam at a national level and competed in the Australian Surf Lifesaving titles for Kurrawa.

She began bodybuilding four years ago, quickly advancing through the state and national titles to compete internationally.

In 2014, Andy married coach Nathan Page in Sydney where they opened their own fitness facility, Fitness Republic.

They sold the business this year and moved back to the Gold Coast.

Mr Page and other members of Andy’s family were too distraught to talk about their loss yesterday and have asked for privacy while they grieve.

Friend and fellow fitness trainer, Asha Burnley, said Andy touched many lives.

“She was a beautiful soul with a kind heart who lived a life of contribution and always wanted to give back, help others and add value,” she said.

“I first met her six or seven years ago, when she was living on the Gold Coast. We shared a mutual love for health, fitness and helping others.

“Her work lately had mostly been as a professional nutritionist as well as competition coaching and running her Isagenix (supplement) business. I am shocked and saddened to learn of her passing.”

Andy, who had just celebrated her second wedding anniversary, was set to co-host a fitness webinar next week.

Colleagues have dedicated the live online event to her memory, calling her a “highly respected and well-regarded coach, mentor, friend and expert in the fitness industry”.

Andy will be farewelled at a private funeral at Somerville Chapel, Nerang on Thursday.

The death is not considered suspicious and a report will be prepared for the Coroner.
