I'm a rather happy customer of Planet Fitness and a regular user. It's pretty clear what their business plan is, but the gym itself is fine, obviously with no frills. The most obvious deficiency is that they only have smith machines and no barbells, but that's not much of an issue for me. The strangest aspect is that there are no scales in the locker room; I assume that's a purposeful part of the atmosphere. Still I recommend them to all my friends. If they don't go, I suppose they're still subsidizing my membership.
