Gyms were allowed to reopen in NSW on June 13, with a limit of one person per four square metres and classes allowed to run with a limit placed on participant numbers.

Livefit Griffith owner Matt Kenny said it was "fantastic" to re-open their doors and with eyes on gyms as part of the last services to resume business, they have to be leading in their response to easing restrictions.

"We're just super ecstatic to be open again," Mr Kenny said.

"We've had to put a lot of procedures in place for people to come back for safety ... What I tell everybody is do what you are used to, but do it a lot more - washing hands, wiping down the equipment more than you usually do and if you are not feeling well, don't come.

"We've got to set an example because people are watching [us as one of the last services to open] ... [but] we are back to doing what we do best, not just myself but all the other places in town as well."

Mr Kenny said the activity at the gym has resumed at the same level as it was before restrictions were put into place, but noted many people were itching for face-to-face training as opposed to virtual sessions which helped the gym continue to operate while doors were closed.

"For me its felt like when we closed, we re-opened and we have taken off where we finished," Mr Kenny said.

"Now its come back, its just felt like everything stopped for three months and has restarted again ... our virtual classes were fantastic and a lot of fun but nothing beats face to face training.

"It was good timing when gyms came back because people were just starting to have enough of that and were ready to come back and have face to face contact ... we're really happy to be back and not just for fitness but for mental health as well ... getting [people] back to a little bit of normality by being able to get back into routine."

According to data from the Heart Foundation, 77 per cent of residents in the Griffith local government area are not physically active enough for good health, with the percentage dropping to 73 per cent across the wider Riverina region.

The Heart Foundation's active living director, adjunct professor Trevor Shilton said regular exercise - such as walking daily - can provide a wide range of benefits.

"When gyms and organised sport shut down due to the pandemic, walking became one of the few options for Australians to stay active," Professor Shilton said.

"Regular physical activity, such as brisk walking for 30 minutes a day, can deliver real health benefits.

"It not only reduces your risk of heart disease and other chronic conditions, but you are likely to feel more energetic, have stronger bones and muscles, and feel happier."
