Would you rather there be one close to home? Distance is a huge factor. How far are you willing to drive? Do you want an all unisex or all men's or woman's gym? Do you prefer a small select group that is tiny and intimate, or a huge chain that has tons of energy and people?
First you have to figure out what type of gym is right for me? Once you answer this, make sure that the gym you choose is convenient enough to where you live or work. No matter how much you love your gym, if it is a huge pain to get there every day, you won't be going as often as you should. Keep that in mind when making your decision.
The easiest way I found to choose a gym that was right for me was asking myself questions. The answers usually help you figure out quite easily where it is that you should really be training.
