4. Do You Really Need That?
Carefully consider fun (read expensive) bells and whistles. Many fancy add-ons go unused and may ultimately be a waste of money. The "extras" that help track distance or time add value only if they inspire you to exercise consistently.

5. Look for Quality
The most important features to look for? Sturdy construction and smooth, quiet operation. Most machines feel fine during the first few minutes, so spend at least 20 minutes trying the machines out. And yes, you need to go to the store prepared to do a workout.

6. Check Out the Best Equipment First
Trying out the top of the line first will give you an idea of what quality looks and feels like. Start your shopping excursion at an exercise equipment specialty store that carries brands you've seen at health clubs. In general, cheap, "bargain" department-store fitness equipment won't cut it.

7. Fit it to Your Body
Nothing you buy should put excessive strain on your back or other joints. Also, look for equipment that adjusts to your height, size and fitness level.

8. Watch Out for Fitness Fads
It may sound good when that guy with the hair talks about it on the infomercial, but it may not deliver what it promises. Beware making a decision based solely on what you see on TV: Equipment that you can't try before you buy is a risky purchase.
