Users and goals: Now that you're certain that an elliptical is your equipment of choice, be sure that the elliptical has an adequate resistance range to enable Mom to use it but also to challenge your 16-year-old runner. You may want to bring everyone shopping to ensure that the trainer accommodates individual goals and heights and weights.
Space available: Determine where you will put your machine and measure the space, including the ceiling height. Take this information with you when you shop and ask the salespeople to ensure the machines you consider will fit. Some well-designed ellipticals are even smaller than comparable treadmills.
Budget: A broad range of equipment exists, with prices from $300 to $6,000. A premium elliptical that will provide long lasting, quality operation generally is in the range of $2,000 and up. Remember, you get what you pay for with fitness equipment, and less definitely is not more here. If the machine feels uncomfortable or breaks down, you won't or can't use it, so that's money wasted. Consider this an important investment in your health and spend accordingly so you can stay fit for years to come.
