Ben Dunne has said he's still not planning to reopen his gyms for now, as he still doesn't believe it's safe to do so.
Gyms were allowed reopen three weeks ago as part of the third phase of easing coronavirus restrictions.
They'd initially been told they would remain close until August under the initial plan, but that date was brought forward under the acceleration of the roadmap.
However, the country's Ben Dunne gyms remain closed, with their website currently suggesting it will be at least September or October before their sites begin opening.
Speaking on Newstalk Breakfast, Mr Dunne said they'll remain closed for as long as necessary - either until the coronavirus is under control, or until there's a treatment or a vaccine.
He said: "We're not planning to reopen the gyms at this stage because I don't think it's safe to reopen a gym in the present state of where the pandemic is.
"One organisation thinks differently to another - I'm not criticising other gyms if they think it's safe to open their gyms.
"I can only speak for my own gyms, and I don't think it's safe for me to open our gyms."
He acknowledged that the viability of gyms with social distancing measures in place is one factor he's considering - but stressed that safety is far and away his primary concern at the moment.
He suggested: "Either we're going to get this virus under control, or get therapeutic treatment... or I will remain closed.
"I'm not in the business of having people get the virus in my clubs."
