I think their business model is quite genius. Get a bunch of fatsos to pay 10 or 20 a month for a gym that most will never use.
Yep, most people don't care about spending $10 a month. Plus they can say they belong to a gym.
I've never been, but I see their commercials advertising $10 monthly membership and from what I hear they buy pizzas once a week. How do they make it? I can't imagine they have personal training. I assume it's all on vending machine junk food sales?
High volume of memberships along with low operating costs.
What do you mean low operating costs? Do the math just for least alone.
I'm sure like most commercial box gyms they run in the red.
Most Planet Fitness clubs I know just pay people Walmart style wages.....the equipment is expensive but when you have about 5000 memberships at 10-20 bucks, a gym pays itself off in less than a year.
