PENRITH is officially in the midst of a fitness craze.
Less than 15 years ago there was a handful of gyms and fitness centres.
Now, there are that many on Henry Street alone — and more than 30 gyms and fitness centres in Penrith.
Some in the fitness industry say the spike has crept up on them; others say it is no surprise, citing the growing population as well as obesity in western Sydney prompting people to get into shape.
But it's not just gyms and fitness centres that have increased.
Personal training services have also skyrocketed, says Denver Oliveux.
He was one of the first personal trainers in Penrith; now there are more than 20.
"We've had a lot of big gyms come here and now with the 24-hour centres popping up I consider Penrith to be among the highest-traffic area for health studios and clubs in Sydney," he said.
"It's a combination of a higher rate of obese people and higher disposable income. We have the biggest chamber of commerce in Australia right here in Penrith.
"It's really cut-throat for gyms.."
Oliveux said gyms and personal trainers weren't in competition but were helping one another as customers lined up in their thousands.
Personal trainers pay rent to be part of gyms and Oliveux said there were at least 20 mobile trainers, who were busy all the time.
"I've always got work and I've got another four guys who work for me," he said.
"Personal training has become popular, especially since the emergence of reality television shows.
"If you drive past Nepean River and Jamison Park early in the morning, personal trainers are using those areas.
"There are a lot of people getting fit — more than you realise."
So when will this surge end?
Mira Donlan, who runs Fit n Fast in Henry Street, said gyms in Penrith weren't bursting at the seams and that there was space for everyone.
Oliveux predicted the influx of gyms would continue for the next few years at least.
"I see it getting bigger, better and more competitive," he said.
"It's great for the area because the more competition, the more choices people have to find a service that's best for them."
