I fail to see how anyone can really complain about this gym. It is practically free - $10 per month. $20 if you want to join multiple locations so you can work out indoors on crappy days either at home or near work like I do. Sure, there are no aerobics classes, there is no pool, etc., etc. But if all you need is somewhere to run on a treadmill or ride a stationary bike a few times a month, I don't know how you can complain about Planet Fitness. Plus, I like the fact that I can run in and not worry in the least what I look like b/c there are no over dressed, overly made up, fancy people. Just ordinary people trying to squeeze in a cheap workout.
Pros: Practically free
Cons: No frills
