This is how many workouts Carla McMillan and Georgia van Tiel do every day.

They do it because they love it, are self-confessed maniacs, and want to be able to, hand-to-heart, recommend the best classes in town.

They need to be able to recommend them because they have launched Bodypass the Australian version of the runaway success that is ClassPass. Bodypass expanded into Brisbane this week,

​The concept allows people to pay a comparatively small amount so they can taste test different classes.

It costs $99 a month for unlimited classes.

Without having to commit to a membership at one gym or studio, it has also opened up an unparalleled flexibility in the way we can exercise.

It has become so successful that some say it has become a victim to its success.

"ClassPass service hits one-year mark with mixed reviews from studios," reads a headline from the Los Angeles Times. "ClassPass: Deep Discounts, but Some Discontent," reads another from the New York Times.

"In New York, where ClassPass first began and is now deeply entrenched in fitness culture, the workout-obsessed say the service is becoming a victim of its success," says The NY Times article.

"As fitness companies attract an influx of new students, studio regulars, who often pay upward of $30 a class or more, are contending with larger crowds, less physically intensive classes and etiquette offences like excess chatter and too-long showers.

"Many ClassPass members say it has grown difficult to get into the desired classes. While studios struggle to find a balance between keeping full-price-paying customers happy and attracting new business, dedicated regulars question whether they should keep paying more than triple what the person pulsing and squeezing next to them is paying."

McMillan and van Tiel are determined to learn from mistakes made in America.

For starters, they are hand-picking the classes.

Brisbane Bodypass partners include RAW Power yoga, Fabulous Yoga and Pilates, BoxR, City Aquatics and Health Centenary and Science of Fitness.

"We have realised the key to health and fitness becoming a part of everyday life means fresh and exciting options. Exercise needs to be fun, accessible, interesting and diverse to appeal to everyone," McMillan says.

Interestingly, the girls, who have been friends for 11 years, say it was not ClassPass that inspired the idea.

In fact, McMillan says she'd never heard of it.

"No, I thought I was a genius," she says when she thought of the idea, saying it had originated from her own class-dabbling.

"I thought, why doesn't something exist where you can visit all your favourite places?"

So she phoned van Tiel, who was living in New York working at a not for profit in charge of running programs to engage the public in health and exercise.

Van Tiel broke the news that the concept was already up and running in New York, so McMillan flew over to try it out.

They agreed that the casual no-strings-attached approach to exercise and studios was working and worth it.

Van Tiel moved home and they hit the ground running, launching in Sydney with the view to roll it out in major cities across the country.

"Variety is key," van Tiel says, adding that it keeps them engaged with exercise and the plan is that the public will feel the same. "We know it's worked for us. We love it."
