A Sydney fitness influencer has revealed she is undergoing emergency brain surgery after being hospitalised for several days.

Barry’s instructor Alicia Beveridge, who was briefly cast on the upcoming season of Married At First Sight before being sensationally cut from the line-up just days before her TV wedding, took to Instagram on Thursday morning to update her followers on her shock health battle.

The popular trainer, known on social media as Sweat with Leash, told fans she had been admitted to Royal North Shore Hospital, where doctors advised immediate surgery.

‘It’s a little too tough on my eyes to film otherwise I would turn up a bit more real and vulnerable,’ she wrote on her Instagram Story.

‘I’m going in for brain surgery this morning and have been in hospital for the past few days. I don’t have all the answers yet, but will explain and show up when I can. Royal North Shore hospital team are incredible.’

The news has left her thousands of followers stunned, many sending messages of love and support as she prepared to undergo surgery.

Barry’s instructor Alicia Beveridge – who was briefly cast on the upcoming season of Married At First Sight before being sensationally cut from the line-up just days before her TV wedding – took to Instagram on Thursday morning to update her followers on her shock health battle

As previously revealed by The Daily Mail, Beveridge was initially cast for the 2026 season of Channel Nine’s ratings juggernaut, with filming scheduled to begin just days later.

‘She was gushing to clients that she was about to walk down the aisle and word even got back to the press,’ one source revealed.

‘She was so excited for the show, but forgot she had signed an NDA. Producers didn’t take kindly to that and decided to cut her and re-cast her at the last minute.’

The shock axing left the Sydney trainer devastated at the time, but she quickly returned to the fitness scene, where she has since built a cult following.

Beveridge is well-known in Sydney’s workout circuit as one of Barry’s Red Room instructors, famed for her high-energy routines and no-nonsense motivation.

Her Barry’s bio reads: ‘From days styling for fashion magazines to years kicking ass in fitness studios, Barry’s is the pinnacle of my sweat career.

In my classes, you can expect high energy, epic tunes and serious party vibes, because there’s nothing I get off on more than being your personal hype girl and butt-kicker.’

She adds: ‘I’ll be your fitness cupid, helping you fall in love with fitness; you’ll lift heavier and run faster than you thought possible.

‘I want my clients to leave the Red Room on a serious endorphin high, like they are leaving a memorable night out with friends – with the added bonus of being a fitter, sexier version of themselves.’
