Our budgets often have line items that we fail to account for, like those irregular large outlays or the mindless little purchases that we make from day to day. But there’s another seemingly innocuous but parasitic part of your spending that you probably don’t pay much attention to: your unused gym membership. We know we should cancel, but we don’t. Why are we spending this money — and how much are we losing? How bad is it? Have you ever noticed how cheap the gym has gotten? How are these places making any money at those prices? Less wear and tear on machines means that the lower price can still cover costs — even the cost of the odd pizza party or visiting masseuse. National Public Radio reports that Planet Fitness, for example, has an average of 6, gum per gym. Most of those gyms only accommodate about people.
