Fitness centers should be willing to offer you a temporary pass for a small daily fee or at no cost. If you know a member of the facility, ask if he or she can get you a guest pass. Consider trying more than one fitness center to make sure you pick the right one.
Don't succumb to a high-pressure sales pitch: think it over. Study the contract carefully. How long of a commitment is required: a year or more, or can you choose a month-to-month arrangement? Can you opt out if you decide it is not the right place for you or if you move to a different city? Do prices vary for peak and off-peak hours? Are there any finance charges or other fees? Don't sign anything you are not comfortable with; remember, there is always another facility.
