A male competitor at an exercise competition has been accused of a ‘dog act’ for ditching his girlfriend after she fainted so he could continue the event.

The incident occurred at the HYROX competition in Sydney last weekend, with footage from a witness going viral on social media.

HYROX is a fitness phenomenon similar to Crossfit, with competitors competing solo or in teams in events that mix endurance and functional strength.

‘That guy’s missus just fainted and like full hit the deck,’ Boundy said over footage of a male competitor running while a woman was being attended to by medics as she lay on the floor.

‘She’s unresponsive and he just kept doing the wall ball [the final exercise] and then crossed the line by himself, he’s left her there.

‘What a piece of s**t.’

Boundy continued to rail against the man after leaving the event.

‘I think I’ve just witnessed one of the worst things in my life. 

‘Some guy’s missus started like falling and fainting at the wall balls and I was like, told one of the judges, can you help her? And they were like what, no, she’s OK, she’s OK.   

‘She was full, like, twitching on the floor. And then her boyfriend kept on doing wall balls, didn’t go over and see her.’

Boundy said the medical teams ‘put barricades’ around the woman as they treated her.

‘The boyfriend walks over, taps her on the leg, and then looks at the judge and goes, “Do I need her to finish the race?”‘

According to Boundy, when the judges told him that technically he didn’t need to finish the event with his partner, the man ‘ran off’ and ‘didn’t even go back and check on her’.

Daily Mail Australia has contacted HYROX Australia for comment.

The video – which also featured on Instagram – drew strong reactions from viewers.

‘If you sign up to do team sports you agree to compete as one … you start together and finish together. I’ve seen friends pull up early in a race and tell their partner to crack on and do a solo. But fainting and fitting on the floor, that’s a no from me. More important things in life than seeing your time pop up on a screen,’ one wrote.

‘This is absolute grounds for breaking up,’ added another, with more commenters labelling the incident a ‘dog act’.

‘Even if I told my husband in this situation to keep toing, if I became unresponsive suddenly I can confidently say he would never leave my side … Girls pick your standards up,’ a third commented.

However, a commenter who claimed to be the woman who fainted gave another version of events. 

‘That girl in the video is me, and my first two questions to my partner when I came to was ‘did you finish it for us, and what time did we get?’ And for context if you bothered to show it, he came back straight away,’ they wrote.

Another commenter claimed the man and woman ‘made an agreement that if she passed out he’d keep going for them both’.

HYROX began in Germany in 2017 and has grown into a worldwide fitness trend, with events held in 12 countries.
