CrossFit founder Greg Glassman has stepped down as chief executive, days after he apologised for his tweet on the killing of an unarmed black man, George Floyd, in the US.
His tweet drew criticism and led to footwear brand Reebok ending its tie up with the fitness company.
"I'm stepping down as CEO of CrossFit Inc, and I have decided to retire.
"On Saturday I created a rift in the CrossFit community and unintentionally hurt many of its members," he said in a statement.
The statement also named Dave Castro as the new CEO of the gym company.
In response to a tweet by research firm Institute for Health Metrics and Evaluation that classified racism and discrimination as public health issue, Mr Glassman had posted on Saturday, "It's FLOYD-19".
The tweet, which equated the police killing of George Floyd to the Covid-19 pandemic, drew flak and led to an apology from Mr Glassman after Adidas-owned Reebok ended its ten-year-old partnership with his company.
Mr Glassman was also reportedly dismissive of the anti-racism protests that followed George Floyd's death in a Zoom call with gym owners.
