Nine host Belinda Russell performs the upside-down splits in the office

She’s the Channel Nine presenter known for her dancing videos on TikTok.

And Belinda Russell showed off her favourite party trick on Tuesday in a viral clip recorded at Nine’s swanky Sydney headquarters.

The mother of three, 44, showed off her flexibility as she took part in a social media challenge that involved performing the upside-down splits. 

Making her feat all the more impressive, Belinda did the splits wearing a pair of red high heels. 

‘My girls told me to try this trend, so thought I’d give it a go when I had a spare minute at work last night,’ Belinda captioned the video. 

‘Really wasn’t sure I’d be able to do it but I love a challenge. Here’s to staying young at heart and not putting limits on ourselves due to age.’
