But, a personal trainer at Glenfield Park's In Motion Fitness said there is still a long road ahead when it comes to educating the population about the importance of a healthy lifestyle.

"It's a substantial amount and I think fitness centres are proving popular in a lot of places as people are starting to take health and wellbeing more seriously and making it a priority," Mick Wainwright said.

"Society is realising that we have a problem on our hands ... the industry has seen huge growth in the last couple of years and it will only move forward with the population growing and new infrastructure.

"Demand needs to be met and hopefully we will see a change in the level of unhealthiness, but there is still a long way to go and it's all about educating people and helping them make the right choices in nutrition and physical activity."

This comes as a proposal was recently lodged with Wagga City Council to convert a building on Forsyth Street into an indoor recreation facility.

A report published in July by Ken Research attributed a number of reasons why the Australian fitness industry has witnessed growth, including an increase in the proportion of those living unhealthy lifestyles, the rise in health consciousness, more household disposable income, fashion trends and marketing strategies.

Mr Wainwright said the growing number of jobs outside of regular hours and a need for more personalised training were other reasons contributing to the rise in services locally.

"The 24 hour gyms are more accessible ... which is really important with today's society as a lot of jobs and positions are going 24 hours; overnight shifts are normal now," he said.

"In the last two to three years, I've really noticed the increase in [gym] availability.

"I've also found that our population is more interested in smaller gyms ... because they get more personalisation; people have a sense of belonging and they find that they get more value rather than just a number in a large gym."
