Olivia Dunne lifts the lid on ‘cardio day’ for LSU gymnastics as the TikTok sensation returns to campus for her senior season after a three-month vacation

Olivia Dunne is back on campus at LSU following an amazing summer break, and the work has already begun ahead of her senior season for the school’s gymnastics team.

The social media star, who has 7.7 million TikTok followers, posted a lighthearted video to the platform that offered a peek into her squad’s ‘cardio day.’

The clip starts with Tigers head coach Jay Clark lip-syncing the audio, ‘Never back down, never what?’

A seemingly exhausted Dunne and her teammates then mouth the words, ‘Never give up,’ before the sequence repeats.

Dunne captioned the TikTok – which has nearly 1 million views at the time of writing – ‘Tigers never back down on cardio day.’

The video comes amid a busy summer for the college gymnast, whose $3.2million NIL valuation from On3 is second only to Bronny James.

Dunne has spent the last three months traveling the world and attending huge events, while also fronting Sports Illustrated ‘s Swimsuit Edition.

This summer alone, the 20-year-old has visited Italy, rode a horse in Texas and partied with NFL legend Rob Gronkowski and his partner Camille Kostek.

‘There’s 104 days of summer vacation til school comes along just to end it,’ she said in an Instagram post recapping her summer.

The TikTok sensation also posed at a Sports Illustrated party showing off her shoot and watched her boyfriend Paul Skenes’ minor-league baseball debut.

Skenes, the No. 1 overall pick in this year’s MLB draft, was also an LSU athlete and recently confirmed the pair’s romance.

Speaking to the Pittsburgh Post-Gazette , he opened up on their relationship and said: ‘It’s nice, for sure. It can be a pain in the butt sometimes, to be honest, in terms of actually going somewhere.

‘If one of us went out in Baton Rouge by ourselves, there’s probably gonna be someone there asking for something — picture, autograph, whatever.

‘It’s nice to be able to have that conversation. She does get it. I do wish she could come to a baseball game and just enjoy it. It does irk me.

‘I don’t have any control over it. She really doesn’t either. I’m sure it’ll get better as I go up levels, but that’s something I want for her.’

Dunne was spotted watching Skenes make his debut for the Single-A Bradenton Marauders last week at LECOM Park.
