Stakeholders are seeking further clarification around what constitutes a gym, as the fitness industry grapples with the latest shutdown measures for non-essential services.
Gyms and indoor sporting venues were among the list of places of social gatherings restricted from opening from noon on Monday.

The measures form part of stage one restrictions imposed by the federal government nationally, in an effort to slow the spread of coronavirus.
However, Anytime Fitness Launceston franchisee Alison Baker said there was uncertainty around the restrictions on services.
"They haven't really made it clear as to what is classes as a gym," she said.
"So, for example, are personal trainers still allowed to take one-on-one clients?
"Are we allowed to take exercise groups outdoors?
"We are a bit uncertain about how limited we are and what services we can still give to members."

According to the latest restrictions, outdoor exercise is still permitted with self-distancing measures being adhered to - including ensuring a 1.5 metre distance between all people.
However, industry association Fitness Australia has sought urgent clarification from the government around the measures, including a clearer definition of "gym".
Chief executive Barrie Elvish said Fitness Australia believed gyms should be classified as essential services, because of their role in maintaining mental and physical health.
"In our push to see this recognised we are working to ensure that all our members continue to comply with relevant guidelines and recommendations as they continue to evolve," Mr Elvish said.
"We are doing everything we can to ensure people keep active and above all else, ensure they are safe."
About 150 members would use Launceston's Anytime Fitness services on a "regular day", Ms Baker said.
After closing its doors on Monday, she said many would be impacted.
"A lot of our members use the gym as a mental health outlet, not just physical health," she said.
"In particular, in the past we have been able to help people out who might have lost their jobs ... so they can come in and do something positive for themselves, without a financial burden.
"There are a lot of members already who have lost their job because of the virus, but now we can't offer them the opportunity.
"I feel quite sad for those people."
On Monday Premier Peter Gutwein said many business would be making sacrifices, but the decision to close non-essential services was necessary to save Tasmanian lives.
