I'm amazed that the described system works / is popular. At first I checked websites of gyms around me, expecting this scheme to be US-only - it isn't. Random UK gym has 8 membership types with 4 different access options (+ 3 different "offers" on top of that) without any price on the web. I've never heard of this before and it seems just crazy... I wonder if anyone checked how many people they would gain / how much money lose by having only 2/3-options with fixed, known prices.
