Who is Mal O’Brien?

“After skipping the 2020 season, 18-year-old O’Brien jumped directly from the 14-15 division into individual competition at the Games last year, and this year she’s proving she’s ready to continue her rise to the top,” writes the CrossFit Games website.

The 18-year-old athlete hails from the US and started training under the watchful eye of five-time Fittest Man on Earth, Mat Fraser, after the 2021 CrossFit Games.

She competed at the CrossFit Games in the Girls (14-15) division in 2018 and 2019, finishing 4th and 5th respectively.

She also became the youngest athlete ever to win an individual CrossFit Games event and was crowned Rookie of the Year.

O’Brien previously trained under James Townsend.
