I like the name "Fitness Factor" that John C suggested the best. I kinda thought of another name based on John's suggestion. How about "Zero to Hero"? But I think I would only use the name "Zero to Hero", if you gym is going to be mostly targeted to guys who do some serious lifting. If your gym is going to be an all inclusive club which offers fitness for everyone in every type of exercise, then I think "Fitness Factor" is the way to go. It's trendy and it covers just about every customer who would be using your gym.
