In a perfect world, factors like time, money, and convenience would never stand in the way of your workouts. But as anyone who’s signed up for a gym membership and never got around to using it knows, that isn't always the case. A new startup aims to make fitness more accessible to people who are unwilling or unable to make a serious financial commitment up front. As Fast Company reports, POPiN lets users at several participating health clubs in New York City pay for gym time by the minute whenever they want.

The concept applies sharing economy principles to the fitness industry. Members with the app on their iPhone or Android phone can choose from four gyms currently partnered with the startup. Each center includes luxurious amenities that are normally exclusive to members paying roughly $200 a month. With POPiN, users can walk in, check in with the front desk, pay $.15 to $.26 for each minute they’re there, and check out before they leave. A 45-minute workout might end up costing them around $8.

The average gym membership goes for nearly $60 a month, and gyms depend on the fact that a significant chunk of their customers let memberships go to waste. POPiN claims it is designed for people who might be more comfortable hitting the treadmill every day one week and taking a break from the gym the next, as opposed to adhering to a strict schedule. With a variety of fitness centers in their system, POPiN also wants to give its users greater access to a diverse range of equipment than they would get with a single gym.

The app has been around for only a few months and is limited to New York City for now, but the long-term plan is to expand to more cities across the country within the year. If you’re still waiting for POPiN to arrive in your area, here are some more app-based ways to improve your exercise regimen today.
