I'm currently a member of Gold's Gym.
I absolutely love it.
I don't know much about Lifestyle Family Fitness, but I've had nothing but good from Gold's Gym.
The cinema in Gold's Gym is seriously a great idea. I biggest problem I'd have with working out is that I'd get so bored so fast. Though occasionally they play terrible movies, it's still entertaining and keeps me on that treadmill.
It's affordable too. I paid an initial $150 start up fee, and now i pay $30 a month.
You get three free meets with personal trainers. They go over your fat to muscle ratio and show you which machines would work best for the areas you'd like to tone. They give you nutrition advice as well. If you enjoy having a personal trainer, you can choose to pay for continued service from them. But even if you don't you can feel free to ask them anything about anything at any time.
