Does it fit my available space? A typical elliptical is about 79 inches long by 30 inches wide by 63 inches tall, and many front-drive elliptical trainers require additional clearance to the rear when in use. Don't forget to measure your ceiling height, too; most ellipticals will add an extra 1.5 feet to your own height.
Does it fit me? If you're especially tall or short, look for an elliptical with a longer or shorter stride length. That said, the only way to know how well any stride length suits you is to get on the machine and exercise for a few minutes. Is the motion comfortable? Do you have plenty of room for your limbs (knees and elbows especially) within the elliptical trainer's frame? If not, look elsewhere. Comfort is key.
Who will use it? If more than one person is going to use the elliptical trainer, everybody should try it out. If the users are of very different sizes, you may need an elliptical trainer with an adjustable stride length to comfortably accommodate all of them.
Should I have it delivered or assembled? When you pick up or receive your elliptical, it will arrive in one or more large, heavy boxes. Often the shippers will deliver boxes to the curb, but won't bring them into your house unless you pay an extra fee for "inside" delivery. If you're handy, patient, and able to get the elliptical trainer into your home on your own (even if that means carrying it piece-by-piece), DIY assembly can be a viable, but time-consuming, option. If you don't have the time or patience to mess with it, consider paying for a professional delivery and assembly service (typically about $100 to $200).
How often will I use the elliptical trainer? If you're committed to long, frequent workout sessions, it pays to invest in a machine with the highest build quality and the most durable parts.
Do I want movable handlebars? Although movable handlebars provide a moderate upper-body cardio workout, many exercisers prefer holding onto the stationary handlebars instead. If you're in the latter group, you can sometimes save money by opting for an elliptical trainer that comes without moving handlebars.
Shop around for the best deal. Online retailers often offer the best price, but reliable customer service can be a gamble. We saw some reports of customers who successfully asked their local retailer to match the price of an online site -- and got the local service, to boot.
Double-check the website. Don't depend on specifications or warranty details from retail websites; these may be inaccurate or out of date. Double-check on the manufacturer's website for more accurate information. If you still have questions, call them for clarification.
