I wonder what the balance is for gyms between active members and non active members. I imagine most successful gyms have a relatively high number of non active members, and if use increased then membership could actually decrease because of crowding issues. I would think the gym's motivation is to increase the number of memberships while keeping actual use low, restricting this kind of investment to expensive specialty gyms. But this idea is successful only if many gyms with many active members are involved. I'm sure this kind of thing will eventually happen, just doesn't seem like the economic motivation is there. But of course I have no actual knowledge about this industry so my ramblings really aren't worth much.
