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 just launched Bodypass the Australian version of the runaway success that is ClassPass.

ClassPass has just celebrated its first anniversary in the States.

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

One hundred dollars gets 10 classes at studios that would ordinarily charge up to $35 for the drop-in rate.

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 1-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.

"We have done every class and can say these are the best studios in Sydney," says McMillan, a yoga teacher who has done studies in natural therapies.

There's altitude training at 3000 feet, Xtend barre, retro aerobics, yoga, Thai boxing, squash, pilates, stand-up paddleboarding, dance, spin and gym classes to choose from.

They say they are being careful not to oversaturate the market, choosing select studios in each area, in hope that people will find their favourites and sign up rather than class hop.

As well as this they are planning on rolling out nutritional advice, bespoke recommendations, Bodypass only workshops and classes.

"It's a premium membership," says van Tiel, who has a degree in human movement. "They're getting a great app, a ton of content, ongoing membership – there's no contract with our membership, but it's ongoing; so month after month, they're getting new classes, new content and really it's a guide to health and wellness ...

"And we want to offer it as a price point where people can afford to do it and they can afford to do it on top of other things like buying a five-class pass or buying a 10 pack or having a membership."

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.

We might not all be workout maniacs, but it does offer a no-strings-attached, playful approach to exercise that is likely to engage even the most tentative.

"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."
