If you're looking to just work out without wanting to be a body builder, this place is for you. Like the commercials state, Planet Fitness is a judgement free zone that totally gets the job done. I'm not a member, but my fellow Yelper Elizabeth D. was a member and I would tag along with her every now and then. Bringing a guest is just one of the awesome perks of PF! And for $10-$20/month?! You can't beat that!
The gym itself is very basic, but still has enough equipment to work on your fitness fully. It may not have as many machines as LA Fitness (my current gym), but you will definitely be able to leave still feeling beat. The equipment they do have is all very clean and new. They maintain everything very well and even use the same equipment company as LA Fitness (Life Fitness). As far as free weights, PF does lack. However, this isn't a gym for meatheads. Free weights only go up to 60 pounds and there are only a few benches. They also have some cables to use. Once again, totally doable if you're looking to just get in shape without hopes of becoming the next bodybuilder. There are also plenty of cardio machines and an area for a "30 minute workout" that consists of certain machines for a full body workout.
I think the best thing about PF is the atmosphere. You don't see the typical gym lunks that LAF is known for. Also, every time we've gone it's been fairly empty making my workout much more enjoyable (we usually go late night on the weekends). The staff is very pleasant and they do a great job at cleaning up and making sure everything looks good. The locker rooms are very nice as well.
