Planet Fitness understands that most people don't go to the gym to become a meathead or a model. They go to lose weight, build energy, and to just feel better about themselves. So it developed the ultimate gym for the everyday peasant. For just $10 a month, Planet Fitness provides the essentials of exercise: free weights, machine weights, and rows and rows of treadmills, bikes, and elliptical machines. It runs by a judgment-free ethic, embracing anyone from the mom hoping to lose 50 pounds to the geriatric recovering from a stroke. There's even a "lunk" alarm that sounds whenever a meathead clangs his weights, letting everyone know that those who call attention to themselves are not the kings of this gym.
